Qt 6.2 introduced an issue where SingleSelection item views would deselect the current item if the user clicked on empty area in the widget. This was very confusing in the scene tree as it was now possible to unselect the current scene. A workaround for this in OBS was added in08e4ee6and expanded on indc30cf0, but being quite hacky it never was the perfect solution. I since dug into Qt and fixed the issue upstream in qt/qtbase@f11e5435c7 for Qt 6.4.3 and newer, so we can remove the workaround when using those versions (with the long term goal of removing the code altogether).
