Gui: fix skip grabMouse on Wayland

[alfrix]

this fixes some instances of the warning message of This plugin supports grabbing the mouse only for popup windows

it seems one instance of this warning remains in the treeview splitter/dragger but i cannot find what causes that one

Anyone able to test it on wayland? @ryankembrey @obelisk79?

@theo-vt is a Wayland user and will test this out.

hi @alfrix! I've looked on the issue page & the forum to find where this error pops up but I can't seem to trigger it, are there specific cases you were looking into?

This happens with the tree in overlay transparent mode

wayland cannot grabmouse i've read that is due to security concerns, so this is specifically needs to be disabled, but long term we may need to rethink the entire functionality and rewrite all the parts that grabMouse or fake a mouse press, which will never work on wayland

Hey! I could not generate the error, I don't know much about display servers so maybe I have some compatibility setting somewhere or something - either way I can't tell if the fix worked or not,
