Steps to reproduce:

Open LibreOffice Writer. I have tested with version 7.6.0.6 64 bits, but I don't think it especially matters:

Write a few words, for example: NVDA is a free screen reader.

Then press control-backspace a couple of times.

Actual behavior:

Untitled 1 — LibreOffice Writer
Untitled 1 - LibreOffice Document  document  editable
blank
speak command keys on
NVDA
is
a
free
screen
reader
ctrl+backspace
dot
ctrl+backspace
reader
ctrl+backspace
space
ctrl+backspace
space
ctrl+backspace
space
ctrl+backspace
space
ctrl+backspace
space
ctrl+backspace

The dot and the word reader were correctly announced, but not the others.

Expected behavior:

ctrl+backspace
dot
ctrl+backspace
reader
ctrl+backspace
screen
ctrl+backspace
free
ctrl+backspace
a
ctrl+backspace
is
ctrl+backspace
sNVDA
ctrl+backspace

Each press of ctrl-backspace should announce the word that is being deleted.
