Characters don't use spinheight while sliding

I'm pretty this used to be the case as 2.1 Rosy explicitly exploited this to get under spin gaps. Possibly broken when implementing the height hook for 2.2.9?

Some pics from the discord:

Characters do use spinheight while in painstate, but they are not allowed passage through gaps unless they are at least as tall as the character's height. This was an intentional decision so as not to allow Fang and Amy to get softlocked on a spindash path by getting knocked into it by an enemy.

Makes sense. I may submit an exception for PF_SLIDING since I don't believe that would lead to any potential softlock scenarios.

Actually, yeah, that would be good!
