On the second keystroke, some input boxes in V2 apps flush whatever value there was and accept values from that 2nd keystroke on...
Try?
Create a new file but do not select 'Create artboard' option.
Go: context bar 'Document setup...', 'Dimensions' tab.
Position cursor in front or in between digits in either X or Y document dimension input box.
Type two digits -> BUG: on second digit, input box empties and the value is replaced by your second digit only.
Why is this problematic?
Unnecessary and unintuitive disruption of the workflow.
No observable benefit of the current behavior.
(Most likely, temporal) loss of user settings.
Annoyance by the fact that one of the oldest known GUI elements in window metaphor UI paradigm has not been implemented properly.
You can play with it. Select a digit then type, select the whole value and type, and so on... This bug has been appearing throughout V2 applications. Some instances are repeatable, some not, which only adds to workflow disruption.
Probably related to...
