Currently RadDocument contains a lot of built-in (latent) table styles, which are always shown in the TableStylesGallery. Introduce API allowing to hide some of them.

Currently when the text contains consecutive non-space symbols like "~!@#$%^&*()_+=-`[]{};:'"/\|., ", each character is detected as a separate word. Instead, they should be considered one word, including all the subsequent space characters.

The following functionalities should respect this grouping:
- Caret navigation by words (CTRL + left/right arrow), MoveCaret UI command and the corresponding DocumentPosition methods.
- Selecting word by double clicking.

When ParagraphProperties dialog is opened while several paragraphs are selected, the values in the dialog correspond to the values of that paragraph, where the cursor was placed before opening the dialog. Then if the dialog is closed with OK button, these values are applied to the other paragraphs as well.

When caret is just after list bullet/numbering and Backspace is pressed, left indent is cleared. Instead, only the bullet should be deleted, and the indent should be kept as it is set.

Possible workaround is to change the document of RadRichTextBox.

When HTML attribute is set and the same property is set in CSS, the element should be styled according to the CSS values, because they have higher priority. For example:
<table border="5" style="border: 1px solid black">

Page field in header (or footer) of document created with mail merge is always evaluated to 1, instead of the number of the current page.

Possible workaround (attached):

- Do mail merges one by one
- Set header/footers anew to contain PAGE fields in each document
- Set FirstPageNumber = 1 to each first section in each document
- Merge with RadDocumentMerger

The memory leak is reproducible when the main thread is too busy to dispose objects used by RadDocument internally. Thus, the RadDocument instances are kept alive in the memory. 

Workaround: When the scenario includes back processing of documents: Start different threads responsible to perform the required operations and use the following code:

Dispatcher dispatcher = Dispatcher.CurrentDispatcher;
dispatcher.BeginInvokeShutdown(DispatcherPriority.Normal);
Dispatcher.Run();

anywhere in the background thread processing the RadDocument.

An useful option would be to export the text without the bullets in it.

The theme color is with higher priority. Thus, when the document is exported to DOCX and opened again, the default color is applied to the style.

When the caret is positioned at the beginning of a paragraph with hanging indent and the user press Backspace, the left indent is set to a negative value, the text goes out of the bounds of the document. 

Workaround:
Use the editor's method instead of the command:

private void RadRichTextBox_CommandExecuting(object sender, CommandExecutingEventArgs e)
{
    bool? parameter = e.CommandParameter as bool?;
    if (parameter != null && parameter == true)
    {
        DeleteCommand command = e.Command as DeleteCommand;
        if (command != null)
        {
            e.Cancel = true;
            this.radRichTextBox.Delete(true);
        }
    }
}

Introduce an option enabling only proportional resizing to be allowed in the ImageSelectionAdorner (side middle thumbs should be disabled). The option can be added in the RadRichTextBox's ImageSelectionAdornerSettings as it already contains CanRotate, CanDrag, CanResize.

Note that Images could also support Lock aspect ratio property, which is different.

Currently, an ArgumentException is thrown when trying to import an image with negative dimensions. In this scenario, we could import the document and skip the image, or read the size of the content.

NullReferenceException is thrown when trying to import a nested hyperlink, e.g. the following OOXML:

<w:hyperlink r:id="rId4" w:history="1">
  <w:hyperlink r:id="rId5" w:history="1">
    <w:r>
      <w:rPr>
        <w:rStyle w:val="Hyperlink"/>
        <w:rFonts w:eastAsia="Times New Roman"/>
      </w:rPr>
      <w:t>google</w:t>
    </w:r>
  </w:hyperlink>
</w:hyperlink>

The Object pool is keeping a references to RadTextBlock and RadRun.

Characters defined with their unicode codes in HTML won't be imported as symbols, but instead of their codes, for example:

<span>&#26009;</span>
<span>&#36039;</span>

Some of these characters are often used, for example for umlauts (Ä, Ö, Ü) and CJK characters.

The hexadecimal code for Zero Width Space character is split into two parts:
<span>&#x200b;</span> results in Ȁb;

Introduce the support for the border property (with type, size, color...) for a span elements.

In OOXML, this looks like:

<w:r>
  <w:rPr>
    <w:rFonts w:eastAsia="Times New Roman"/>
    <w:sz w:val="45"/>
    <w:szCs w:val="45"/>
    <w:bdr w:val="single" w:sz="12" w:space="0" w:color="000000" w:frame="1"/>
  </w:rPr>
  <w:t>Div with border for Telerik</w:t>
</w:r>
<w:r>

- When a floating image is inserted into header/footer the image is clipped. However, if Enter is pressed in the header/footer later, the whole image is shown. Further, if Enter is pressed again, the image is clipped again.
- When floating images are placed in a header or footer, and are positioned outside of the text editor's area, they are not visualized. MS Word visualizes such images as slightly grayed out (similar to watermarks) in normal mode, and always visualizes them in Header/Footer edit mode.
