Auto-Lock and Timer

So, if your timer is set to the same length of time as your auto-lock, the timer alert won't go off. The timer simply ends and goes back to looking as though a timer was never set in the first place. I've tested this by changing the auto-lock time and the timer length.

If the timer's set to 1 min and my auto-lock is too, it won't make the sound at 1 min or at all, the timer simply ends.

If the timer's set to 2 mins and my auto-lock is set to 1 min, the screen will still lock, then the timer will go off with the noise as it should after another minute.

If the timer's set to 1 min and the auto-lock is 2 mins, then the timer will still go off while the screen's active. I checked that just in case it was an issue with the timer at 1 min regardless of auto-lock. If the auto-lock isn't triggered, like I get a notification or something that keeps the screen active, the 1 min timer will still work appropriately.

Anyone else experiencing this issue?
