screen recording of the bug

SUMMARY
When switching virtual desktop using the touchscreen gesture (three fingers right/left swipe on the touchscreen), the Edit Mode gets triggered, making the gesture useless as everytime you would need to manually exit edit mode. This does not happen using the touchpad gesture to change virtual desktop.

(Bonus bug, the edit mode popup is not centered, but it's only a visual problem, so nothing serious)


STEPS TO REPRODUCE
1. use Plasma 6 on a device with a touchscreen (HP 2-in-1 laptop-tablet in my case)
2. create a second virtual desktop and place a window there
3. change virtual desktop using the three fingers swipe gesture on the touchscreen

OBSERVED RESULT
Edit mode is triggered

EXPECTED RESULT
Edit mode is not triggered

SOFTWARE/OS VERSIONS

forgot to mention, this did not happen in Plasma 5, so it's a plasma 6 only problem

Should this bug be closed? I note that it was marked as a duplicate of 482222 before a bunch of others were marked as a duplicate of this one. Moreover, the bug unfortunately was never really fixed in 482222 or upstream in Qt, as the problem is still alive and well (see https://bugs.kde.org/show_bug.cgi?id=497076 and https://discuss.kde.org/t/3-finger-gestures-on-touchscreen-bug/15956/14).

I am able to reproduce the issue with three finger tap entering Edit Mode on git-master

If I quickly tap with three fingers and swipe:
- Sometimes the gesture works as expected and the virtual desktop is switched
- Sometimes I briefly see Edit Mode, but then the virtual desktop is switched.

If I just tap with 3 fingers in the middle of the desktop, it goes into Edit Mode more often than not

related to https://bugs.kde.org/show_bug.cgi?id=482222  is probably a qtquick bug not forwardning touchcancel events, see https://codereview.qt-project.org/c/qt/qtdeclarative/+/589794
