So you don't think the hide invisibility ends when the conditions for hiding no longer apply?
I have hard time gauging from your posts what you think this RAI that is so obvious even is, beyond, just ignore the rules and rule what seems sensible, which is not a ringing endorsement for the quality of the rules. I can do that without any rules, so there is no need to pay WotC for it.
Sorry, didn't realize you had missed all of my earlier posts on this.
If a PC hides, then quickly moves from cover to cover on their turn, they continue to benefit from the hide action.
If a PC hides, then slips out from an empty room, behind a guard patrol, and down a different hallway, they continue to benefit from the hide action.
If a PC hides, then scrambles up to cling to the ceiling as a guard patrol rounds the corner and passes under them, they continue to benefit from the hide action.
If a PC hides, then rushes out of cover to stab a guard in the back, then they lose the benefits of the hide action after their attack.
If a PC hides, then bursts out of cover in front of a guard, makes funny faces at them, flips them the double bird, then darts down a hallway... they do not continue to have the benefits of the hide action unless they make a new stealth check.
