Yes, I can even reproduce it in my example once I select the 'AllEditKeys'.

Is there a particular reason why you want to set it to AllEditKeys?

By default it is set to DoubleClicked|EditKeyPressed|AnyKeyPressed, which I find works reasonable.

Have you tried a different input widget instead of line edit? Maybe those are better for customizing the behavior you want.

sorry I can't be of more help.
