Link to issue number:

Fixes #13899

Summary of the issue:

Using Notepad on Windows 11, performing Say All (nvda+downArrow|nvda+a) selects each line of text.

This is because UIATextInfo.updateCaret = UIATextInfo.updateSelection, so updating the caret sets the selection.

The same problem exists with MSHTMLTextInfo

Description of user facing changes

Say All no longer highlights each line of text.

Description of development approach

1. Copy the text info
2. Collapse the new text info (e.g the range endpoints become (start, start))
3. Set the selection on the new range

Testing strategy:

Test with STR in #13899 with Notepad
Test Say All with Internet Explorer as well.
