Summary:
The KCM has a context property of the currently set theme index. This is
set before the decorations model is populated, so it is currently always
-1.
This model is populated after the constructor but before
KCModule::load().
KCModule::load is called from KCModule::showEvent so before
QQuickGridView will start doing anything with delegates.
This fixes the problem simply and also avoid parsing the config file
multiple times.
This bug was introduced in 5.9.4:
Someone made a (tested) change to make sure the view scrolled to the
right place on startup.
I then made a (tested) commit fixing the crash on exit
The author then updated his patch to my changes, but now in a way that
didn't work.
Test Plan:
Opened system settings module with a million decorations.
The correct entry was visible and highlighted.
