A screen that closes "on a key" closes at once when the key is still held

Symptoms

Captures of the same action disagree: after F1 some show the help screen, others the menu as if nothing happened.

Cause

POD's help loop draws the picture until FUN_004a2bf0 finds a menu key held, and F1 is one of them. If F1 is still down when the loop first checks, the help closes at once; only a quick tap shows it. Then FUN_004a2e04 waits until every key is let go.

What to do

Read whether a wait tests "held" or "newly pressed" before porting it, and port that test. In frame tests, accept both outcomes where the original's depends on how long a key was held, and continue the sequence from the one the capture shows.
