Replay Theater - Escape behaves inconsistently

Escape behaves inconsistently

Summary: When starting up a team battle replay in the replay theater, during the character roulette pressing the escape key (on the keyboard) will do nothing. Pressing the Back button with mouse will instantly cancel the replay. When watching a team battle replay in the replay theater, pressing the escape key will bring up the escape menu, while pressing the back button will show a “Leave this replay?”-prompt. These inconsistencies are mildly confusing, and the very first thing should definitely be a bug at least.

Edit: The back button during character roulette only shows up in the TVs, not in my replays or favourites. In my replays and favourites, you seemingly cannot quit out of character roulette at all.
