Strange behaviour of QtQuick ToolBar within QML editor

If the editor cursor is placed onto an item where the small lightbulb after this item occurs (Rectangle, Text, TextInput and so on) and the whole word is marked and deleted by pressing the delete key the light bulb stays where it was.

Additionally you can still click the lightbulb to bring up the QtQuick ToolBar. If you change some settings with the ToolBar now the first change is accepted and misplaced within the code. Further changes are completely ignored.

I think, the lightbulb either has to be removed after a deletion or it should check the content right before the cursor position. (It seems as if it does when you simply delete one letter or a part of the Item)
