### Bug report

When adding a <select> element as a custom tool in the Editor, the dropdown does not open.

### Reproduction of the problem

1) Run the Dojo sample and try to open the dropdown in the toolbar:

https://dojo.telerik.com/VVPUopDw

The same example work as expected with version 2023.1.117.

2) When using version 2024.4.1112, if you remove the "ref-toolbar-tool" attribute from the <div class='k-toolbar-item'> element, the dropdown opens as expected.

### Expected/desired behavior

The <select> element must function correctly when added as a custom tool in the toolbar.

### Workaround

Handle the "click" event of the select and prevent the event bubbling:

<script>
    $(function () {
        const selectElements = $('select[id^="symbolSelect_"]');
        $(selectElements).each(function (index) {
            this.addEventListener("click", clickHandlerSymbolSelect);
        });
    });

    function clickHandlerSymbolSelect(e) {
        e.stopPropagation(); //Prevent event bubbling, so Kendo cannot swallow or cancel the event.
        const sendingElement = e.target;
        sendingElement.showPicker();
        return true;
    }
</script>

Referenced in this commit

Reproduction of the problem

1. Define an Editor and enable the ImageBrowser feature:
   Open this REPL example

Expected/desired behavior

TicketID:

Environment

• **Telerik UI for ASP.NET Core version: 2025.1.227
• **Browser: [all]

### Bug report

The File() option of the Editor's FileBrowser configuration does not provide UrlHandler() option, which is available for the ImageBrowser.

### Reproduction of the problem

1) Define an Editor and enable the FileBrowser feature:

@(Html.Kendo().Editor()
    .Name("Description")
    .Tools(tools => tools
        .Clear()
        .InsertFile()
    )
    .FileBrowser(fileBrowser => fileBrowser
        .File("GetFile", "FileBrowser", new { path = "{0}" })
        .Read("Read", "FileBrowser")
        .Create("Create", "FileBrowser")
        .Destroy("Destroy", "FileBrowser")
        .Upload("Upload", "FileBrowser")
        )
)

2) The File() option sets URL responsible for serving the original file. Try to set it by using a JavaScript handler.

3) The File(x => x.UrlHandler("setURLHandler")) configuration is not available.

### Expected/desired behavior

The UrlHandler() function must be available to set the URL that serves the file using a JavaScript handler.

### Environment

Bug report

Reproduction of the problem

Open this dojo example: https://dojo.telerik.com/BzNkZgSf

1. Run the example
2. Click the Insert Hyperlink tool in the Editor
3. When the hyperlink dialog appears, hover the inputs in the dialog

Current behavior

The input tooltip shows:

k-editor-link-url

because the input's title attribute is set like this: title="k-editor-link-url"

Expected/desired behavior

Instead of the name of a class, the tooltip should show "Web address", "Text", or "ToolTip" respectively.

Environment

• Kendo UI version: 2022.3.806
• jQuery version: x.y
• Browser: [all]

Bug report

CustomTool does not expose an Icon() API configuration in the Editor

Current behavior

Currently, defining a custom tool does not enable you to specify an icon which tends to be permitted in the Kendo UI for jQuery Editor incarnation. For example:

$("#editor").kendoEditor({
    tools: [
        {
            name: "Toggle",
            icon: "toggle-full-screen-mode"
        }
    ]
});

The following dojo showcases this behavior.

Expected/desired behavior

It would be beneficial if there is a possibility to explicitly define an icon in the MVC and Core wrappers. For instance:

@(Html.Kendo().Editor()
    .Name("editor")
    .Tools(tools => tools
        .Clear()
        .CustomButton(button => button
            .Name("ToggleFullScreen")
            .Icon("toggle-full-screen-mode")
        )
    )
)

Environment

• Kendo UI version: 2023.1.1114
• Browser: [all]

### Bug report

When adding a custom tool with a template in the Editor, the hash-template syntax is treated as a string.

### Reproduction of the problem

A Dojo sample for reproduction: https://dojo.telerik.com/iwikOpul

### Expected/desired behavior

The hash literals should be parsed correctly to display the respective data.

### Environment

* **Kendo UI version: 2023.1.314
* **Browser: [all]

Bug report

The ExportAs command's dropdown options are not populated when the client-side exportAs configuration of the Editor is additionally configured.

Regression introduced with 2023.1.314

Reproduction of the problem

1. Open the following dojo
2. Notice that the dropdown is blank and no data is populated.

Current behavior

The ExportAs command's dropdown is blank.

Expected/desired behavior

The ExportAs command's dropdown data should not be blank.

Environment

• Kendo UI version: 2023.1.314
• Browser: [all]

Bug report

We are trying to prevent users from dropping an image file from their computer directly onto the Editor with Firefox. When this happens the browser converts the image into a uri encoded version of the image. When we define a custom PasteCleanup function to handle this, the Editor will sometimes work as expected but other times it will throw an error when trying to execute the function. This seems to be random after each page load.

Reproduction of the problem

1. Open this Dojo with Firefox
2. Run the Dojo and drag and drop an image from your machine

Please note that the reproduction of the error is inconsistent. However the CustomPasteCleanUp doesn't prevent the addition of the image, nor does the prevention of the Drop event.

Screen capture of reproduction in ASP .NET Core.
Screen capture of reproduction in Dojo.
More information about issue and reproduction available in ticket: 1534730

Current behavior

An image file that is dragged and drop by the user to the Editor is always added to the widget.

Expected/desired behavior

The current behavior should be preventable and an error must not occur.

Environment

• Kendo UI version: 2021.2.616
• Browser: [ Chrome 93 | Firefox 92 ]

Currently, the ExportAs configuration exposes Proxy method to setup the proxyUrl field, but it is limited to enter only action and controller. Whereas in RazorPages a URL with handler should be defined instead. 

Plus, in order for the AntiForgeryToken to work properly it should be injected in the form submitted by the tool.

Bug report

When the Editor is configured by using tagHelpers and the configuration of the tools is on multiple lines additional new lines are added to the Editor content due to the tags used for the tool's configuration.

Reproduction of the problem

1. In UI for ASP.NET Core app use the following Editor configuration:

<button onclick="getValue()">get Value</button>
Test-1:<br /><br /><br /><br />
<kendo-editor name="test1" tag="div" >         
    <tools>
        <tool name="viewHtml" />
    </tools>
</kendo-editor>  

<script>
    function getValue() {
          var editor1 = $("#test1").data("kendoEditor");
          console.log(editor1.value())                   
    };
</script>

2. Enter for example "1"
3. Click the 'get Value' button

Current behavior

The value of the editor has additional new lines. The additional lines could be observed also in the 'viewhtml' tool. (screencast)

Expected/desired behavior

There should be no additional new lines added to the Editor's content.

Workaround

Configure the Editor on a single line

<kendo-editor name="test1" tag="div"><tools><tool name="viewHtml" /></tools></kendo-editor>

Environment

• Kendo UI version: 2021.1.119
