Comment 12 for bug 1756995

Yes, but I don't know if it should be fixed like this (maybe using some constant for "<...>") or we might want to remove the evaluation from losing focus.
I didn't test, but I guess this might also fix it.

If you type in a complex formula and change to another control, should it be evaluated?
If you made a mistake, you can't fix it (because it is already evaluated).
On the other hand... if it doesn't get evaluated, you probably won't see that it was wrong.
And then you also have to re-type after re-opening the dialog.
