Frame-dropping out of a respawn wave

I've had this happen 3 times so far. I'll be sitting in the spawn menu, watching the wave timer count down with my loadout already set, spectating an ally... and a long framedrop will occur somewhere around the latter half of the "0s" final second of respawning, and I'll skip straight to spectating and queueing for the subsequent wave.

This is an extremely rare issue, but the fact that it happens at all is concerning.

This happens very frequently for me, the same effect occurs when spectating between different players.
