I have managed to break that with implementation of #11369.
Obviously it is a bad idea to change selection in a slot connected to model's rowsInserted signals
because the drag'n'drop does not work properly anymore. Now registry bridge will emit a signal after
new layers have been added, so the selection change at that point should be safe.
* respect the 'auto enable otf' setting
* don't ask if otf is off or for layers without geometry
* ask when otf was switched on
* show more information in selection dialog
