Description

WHAT: accessibility bug (regression) in Gutenberg 19.2 - it was not present in 19.1, occurs with JAWS screen reader version 2024.
When writing a new content -post, page, etc.- and having an empty paragraph block, writing some text. Typing is regular, but then, when selecting text, the first word is never spoken and JAWS says "edit box, empty" instead of saying the currently select word; then, selecting further words, they are spoken correctly. Affected also the ctrl+a ("select all") command.
Current result: when editing text, first character/word selected is not spoken by JAWS, while subsequent text is read regularly.
Expected result: every character/word selected, is regularly pronounced by HAWS screen reader.

Step-by-step reproduction instructions

Pre-requirements: Windows 10 or 11, JAWS screen reader 2024 latest build. Browsers, any browser.

1. activate Gutenberg 19.2 plugin
2. create a new content - post, page, it's the same.
3. type a single character, then select it with shift+arrows. JAWS screen reader won't read it. Let's take as a sample, to write the number "1".
4. after the "1", write a "2". Then, select the "2", it won't read it. But it'll then read the "1" typed before, as it'll be the second character selected sequentially.
5. Try the same flow with words. And then, with the "select all" (ctrl+a keystroke) in the single block.
