When a span element's opening and closing tags are on different lines in the HTML and there is no content in the span, it should be imported as a single space.

For example, the following HTML:

test,<span>
</span>test<span> 

should be imported as

test, test


Note: If there is content in the span that is split between the lines, it is correctly imported:
test,<span>a
</span>test<span> 

results in

test,a test

<samp> HTML element could be imported as span with specific formatting. Currently it's just ommited.

When RadRichTextBox for WPF is hosted in a WinForms application (through ElementHost), typing with Japanese IME duplicates the typed letters, which makes the control unusable with the default behavior.

Possible workaround: Create custom caret. There are some suggestions in this forum thread: https://www.telerik.com/forums/richtextbox-doesn't-support-japanese-ime-when-hosted-in-winforms

Switching between bulleted and numbered lists only affects current paragraph instead of changing the list for all paragraphs currently included in it.

Steps to reproduce
1. Create a numbered list with several items
2. Click the bulleted list button
Expected behavior: The entire list switches from numbered to bulleted
Actual behavior: The current list item switches to bulleted but the rest of the list remains numbered.


Workaround: When the ToggleBulletsCommand is executed, traverse the PreviousSiblings and NextSiblings of the current paragraph and change their list properties if they belong to the same list. Sample code attached. Note: the workaround will change the list properties only for the consecutive paragraphs of the same list and will create a selection to do so.

The content of the table cells seems to be rendered in the correct position while the borders are drawn above the continues section break.

Implement Auto Text gallery for inserting text. More information related to Auto Text can be found on the following post:

When copying the formatting using span to span selection, any formatting applied with a character style is lost. 

When selection is applied quick after format painter is clicked formatting is not applied.

The Outline view shows the content of a document as bulleted points. It enables the user to easily move whole paragraphs within the document or to create headings.

Allow the customers to change the properties defined in the default stylesheet. They need to change properties like font size, font family, border-spacing, line-spacing, as in RadRichTextBox they might be different from the ones used by the browsers.

Loading large documents freezes the UI. Instead, the document could be imported and measured asynchronously in a background thread, and some progress indicator shown to the user.

Note: Image sources should be frozen when the document is loaded in a background thread.

Workaround: Following the steps:

- Import the document in a background thread using the specific format provider. 

- Freeze all images in the document using the methods in the attached file.

- Set the document to RadRichTextBox in the main thread using a dispatcher:

this.Dispatcher.Invoke(new Action(() =>
{
    this.radRichTextBox.Document = document;
}));

Implement an option for the customers to split a document into two views, allowing them to edit and view different parts of the document at the same time.

When a hyperlink (and only the hyperlink) is selected, and the user types over the selection, the hyperlink is deleted, and text with locally set blue fore color and blue underline is inserted. 

Instead, the hyperlink should be preserved, and just its link text should be modified.

The custom list styles from a document exported by RadRichTextBox's HtmlFormatProvider are not imported.

Annotation Ranges where SkipPositionBefore is set to false on the AnnotationRangeEnd cause cursor jumps when deleting content to the right of the Annotation Range.

Steps to reproduce:
1. Open a job with Annotation Ranges where SkipPositionBefore is set to false on the AnnotationRangeEnd (I used the Document Protection sample in the demo app)
2. Move your cursor to the end of the range.
3. Hit the delete key
Expected: The cursor remains at the end of the AnnotationRange and content to the right is deleted.
Actual: Content to the right is deleted but eventually the cursor will jump to the right by one position and end up outside the Annotation Range.

When there is a hyperlink enclosed in another annotation (e.g comment, bookmark, read-only range), and the user moves the caret position just before or just after the hyperlink, and starts typing there, the text is inserted with the style of the hyperlink (by default, blue with blue underline). Instead, the text should be inserted without such style.

The TxtFormatProvider always imports the document with UTF8 encoding. It will be great if users could change this setting in order to import document with different encodings.

Deleting table right after merged fields are updated causes StackOverflowException.

The caret gets a wrong size when positioned on annotation start/end.

Currently, RadRichTextBox only imports from HTML documents tables with spacing between cells, but it does not export tables with such style. It seems like the border-collapse: collapse value defined in the Table Normal style overrides the border-spacing value, which is applied to the cells.
As a workaround, the document styles can be omitted from the exported HTML and the styling can be exported inline be changing the ExportSettings of HtmlFormatProvider:
provider.ExportSettings.StylesExportMode = StylesExportMode.Inline;
provider.ExportSettings.StyleRepositoryExportMode = StyleRepositoryExportMode.DontExportStyles;
