Description : 
When you click before the content in the Editor, the cursor should show up before the text. But, if a text was added programmatically, the cursor shows up after the added text instead.

To reproduce the problem :

1. Open this REPL example: https://blazorrepl.telerik.com/cdYpPabd37jvK9jt23

2. Click the "Insert Inline Text" button.

3. Try to place the cursor in front of the editor content.

We have a survey page that has multiple editor fields in it.  They need to accept rich text from a paste or other keyboard commands, but we do not want to waste the vertical space for the toolbar appearing in each editor field.

Please update the editor to hide the toolbar if the List<IEditorTool> collection is empty.

This change would make it much easier and less fragile than removing the toolbar to through Css.

I have the following command

await _editorRef.ExecuteAsync(new HtmlCommandArgs("insertHtml", "<hr class='donotremove' />", false));

Currently, the <hr/> element is added but its class is stripped. This is not the case with other elements. 

Reproduction: https://blazorrepl.telerik.com/GRYyGUbH492QNMki44.

Please allow adding class to <hr/> elements, too.

Currently, our Editor component does not support a placeholder parameter. Having a placeholder parameter, similar to the Kendo UI Editor, would prove to be beneficial.

Hello,

We've come across a bug. It seems as whatever tool button(s) that should be selected is not shown correctly. It appears to show the previously selected.

Repro steps:

1. Write two different formatted texts on separate lines in your Editor component.
2. Move the cursor to the first line
3. Move the cursor to the second line that has a different formatted text. Note that the tool button for the formatted text on the first line is shown as selected.
   
   This should happen:
   

Is this an intended behaviour? Our users are confused :)

It seems that texts/options in the Format tool dropdown are not part of the localization (Paragraph, Heading 1..6).

Editor demo

I cannot clear the content area of the TelerikEditor when the component is placed in the Form Item Template.

<AdminEdit>

Below, you can find a workaround solution:

@using System.ComponentModel.DataAnnotations;
@using Telerik.Blazor.Components.Editor

<TelerikForm Model="@Model" OnSubmit="@OnSubmitHandler">
    <FormValidation>
        <DataAnnotationsValidator />
        <ValidationSummary />
    </FormValidation>
    <FormItems>
        <FormItem>
            <Template>
                <TelerikEditor @bind-Value="@Model.Name" @ref="@EditorRef" />
            </Template>
        </FormItem>
    </FormItems>
</TelerikForm>

@code {
    public SampleData Model { get; set; } = new SampleData();
    public TelerikEditor EditorRef { get; set; }

    private async Task OnSubmitHandler(EditContext editContext)
    {
        bool isFormValid = editContext.Validate();

        if (isFormValid)
        {
            //some logic here
        }
        else
        {
            await EditorRef.ExecuteAsync(new HtmlCommandArgs("setHtml", "")); //workaround

            //clear the content of the editor to let the user type anew
            Model.Name = String.Empty;
        }
    }

    public class SampleData
    {
        [Required]
        [MinLength(30, ErrorMessage = "The content should be minimum 30 characters long.")]
        public string Name { get; set; }
    }
}

Hello,

We are adding references to other documents via a drag an drop over the text as a superscript hyperlinks. Our users are complaining that when we drag and drop onto the Blazor editor control, it is hard to see exactly where the drop is going to be.

The Kendo UI Editor supports this.

Please expose the ability to allow additional HTML attributes in the Editor content.

===ADMIN EDIT===

Provide support for:

• custom attributes for the Editor elements
• custom tags

When I add table to Editor, dispose the component and initialize it again with the same content, the table cells appear taller. It looks like an additional <br class="ProseMirror-trailingBreak"> appears in every cell.

Reproduction: https://blazorrepl.telerik.com/cwaqcSuV12myl9ok47.

Steps to reproduce:

1. Add a table
2. Toggle the Editor
3. Cells appear taller

Please add built-in toolbar tools (buttons) for Cut, Copy and Paste.

The request from our customer is to have similar behavior as typical toolbars in most applications where there is a cut and paste along with the regular keyboard shortcuts.

As the toolbar options typically show the options that are available then one might presume that because cut and paste icons are not present then such a shortcut might not be available either.

Here is a scenario that produces an exception.

1. Go to https://demos.telerik.com/blazor-ui/editor/overview
2. Select the image in the Editor and resize it using the border / resize handles.
3. Keep the image selected and then click the "Insert image" button in the toolbar of the editor. Now the page will crash.

In Editors that use the ProseMirror engine (including non-Telerik), when you click Enter twice in the middle of formatted text and go back (with an up arrow) to write, the new text format is back to default.

This enhancement will allow you to keep the text format after pressing Enter and creating new block elements.

It would be great in a future release if we could paste in images from the clipboard.

Highlight an existing hyperlink and click the Insert Hyperlink button. The update button is empty

Hello,

I expect Shift + Ins to behave like a standard paste (Ctrl + V), but instead, it behaves like a plain text paste (Ctrl + Shift+ V).

Hello,

If the Edtor content includes <br /> tags, they will be lost if the user copy-pastes them to a plain text environment such as Notepad or a <textarea>.
