It's not an issue/bug.

Here's a bit of very simple math.

1250 (Exclamation Mark Range) - 725 (Jump Range) = 525

Rengar's movespeed in stealth moving towards you with Youmuu's on or a Triforce, or similar ms item will be over 525 for sure.

That gives you under a second to react as ms is in game units covered per second. Possibly closer to 0.5 due to the speed that he can ahieve with all ms items active.

I think we can assume a small amount of human error and exaggeration in your statement too, so it seems that Rengar was intended to give just as much warning as you're getting.
