Context menu items no longer selectable while holding right click
Before 3.38 it was possible to hold the right click that was used to open a context menu, then hover over a menu item and release the button to select the item. Now it is no longer possible to select menu items this way.
This affects gtk3 context menus, but does not seem to affect the Firefox context menu.
I've bisected this issue to the following commit: mutter@79050004
