When code template window is displayed with a reduced size (selection already narrowed) and the the selection is expanded by deleting letters, the window size is not increased.
The following code templates exist:
Type “tes” and open code templates. Only “test” is suggested, the size of the window allows to display that single item.
Press backspace, so now you have “te”. You can navigate between the three templates now using cursor keys, but only one is displayed at a time.
I think the window should either increase its size when the number of elements grows, or you could always display it with the full size even when there are only few elements to display.
Can you reproduce this?
