Hello! I have tried to reproduce the issue using firefox 109.0a1 (2022-12-06) on Ubuntu 22.04 but unfortunately I wasn't able to reproduce it on my end.
Could you please answer the following questions in order to further investigate this issue?

1. Does this issue happen with a new profile? Here is a link on how to create one: https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles
2. Does this issue happen in the latest nightly? Here is a link from where you can download it: https://www.mozilla.org/en-US/firefox/channel/desktop/
3. Do you have any addons installed if so can you list them?

1. Yes, issue still happens with new profile.
2. Tested with latest nightly (Build ID 20221206034609).
3. No addons in new profile.

Also it can be reproduced without scrolling selected text out of view:

1. Go to about:support.
2. Scroll all the way to bottom.
3. Select any text and press "space".

Might be only KDE wayland specific.
Doesn't happen on chromium wayland.

I can repro fwiw, that means that we're somehow getting touch events or so? That's weird. The code for this is layout/base/AccessibleCaretManager.cpp
