Describe the bug

The bug described in issue #11390 for TextBox is still present for the SelectableTextBlock.

To Reproduce

Double click to select a word. Then a single click on that word does not reset the selection.

Expected behavior

The selection should be reset during the single click.

Avalonia version

11.0.10

OS

Windows

Additional context

It was fixed for TextBox by #11294. Specifically, I believe the problem lies in the OnPointerPressed method. The statement here in "SelectableTextBlock.cs" was removed from "TextBox.cs":

That PR contains some other changes to the word selection code that didn't make it through to "SelectableTextBlock.cs". I don't know if any of that is relevant or just refactoring.
