ADA Desktop App: Jaws reads "blank" when backspacing to delete text in a long draft post

Description

Reproduced on desktop app 4.2.3 on Win 10, v5.15 RC2 (does not reproduce on Chrome browser)

Steps:
1. Copy this text and past into the message input box
```
do you know a tool for detecting SQLi in a whole website┬┐? I mean, I want it to crawl it and then just test a few payloads (', %27, waitfor delay '0:0:05') , and detect which URL, parameter is vulnerable. Best thing I found is this thing
```
2. With Jaws running, backspace to delete the characters on the last line of the draft post
3. With Jaws running, continue to backspace to the 2nd last line of the draft post

Observed:
2) Jaws reads the characters as you backspace to delete the last line of the draft, but
3) Jaws starts to read "blank, blank, blank" once you've backspaced to the 2nd last line of the draft post and continue to backspace

Expected:
Jaws reads characters as you backspace to delete a long draft post
