SUMMARY

In Plasma Mobile, we have been dealing with a bug with the virtual keyboard, where when we unfocus on a text field in the shell, the vkbd reopens unselected to anything. This appears to happen to text fields in plasmashell, but not in apps...

STEPS TO REPRODUCE
1. Launch Plasma Mobile
2. Swipe down to go to the search view (maliit opens)
3. Swipe up to go back to homescreen (maliit closes)

OBSERVED RESULT

Maliit reopens for some reason after closing.

EXPECTED RESULT

Maliit closes and doesn't reopen.

Hmm, it might actually be a change on the Qt side related to how focus works, because it only seems to happen to those text fields (which have a lot of logic behind automatically focusing them when views open/close). I'm going to close this for now because looking at wayland logs I didn't see anything wrong with how kwin was handling it
