Bug report

The TagHelper Grid's TagHelper is not correctly serialized and cannot be used to export hidden columns.

Reproduction of the problem

• Set the exportable TagHelper for a hidden column to enabled.

<columns>
    <column field="Discontinued" hidden="true">
         <exportable enabled="true" />
    </column>
</columns>			  

• Open the following REPL example.
• Export the Grid and observe the exported document.

Current behavior

The Grid TagHelper does not export hidden columns if the exportable TagHelper is enabled identically to the Kendo UI for jQuery Grid column exportable option.

Expected/desired behavior

The Grid TagHelper should be able to export hidden columns if the exportable TagHelper is enabled identically to the Kendo UI for jQuery Grid column exportable option.

Environment

• Kendo UI version: 2022.3.1109
• Browser: [all]

### Bug report

The attributes set through the "HtmlAttributes", "ContentHtmlAttributes", and "LinkHtmlAttributes"methods are not applied to the TreeView items.

### Reproduction of the problem

1. Create a TreeView and set attributes by using the "HtmlAttributes", "ContentHtmlAttributes", "LinkHtmlAttributes"methods:

@(Html.Kendo().TreeView()
    .Name("treeview-kendo2")
    .Items(treeview =>
    {
        treeview.Add().Text("My Documents")
        .SpriteCssClasses("k-icon k-i-globe")
        .Expanded(true)
        .Url("/")
        .HtmlAttributes(new { @class = "fairydust1" })
        .ContentHtmlAttributes(new { data_navigate = "navigate_content", @class = "trigger", title = "content_title" })
        .LinkHtmlAttributes(new { data_navigate = "navigate_link", @class = "trigger", title = "content_link" });
    })
)

2. Run the page and inspect the TreeView item.

### Expected/desired behavior

The attributes are serialized and rendered.
