[Bug] disable_when() appears to be optimized out when used in function partway up the call stack

[MagmarFire]

I'm encountering a strange issue where a use of disable_when() does not get applied when I use it in one function but not another. Please refer to the following code:

I expect this to create a ResetNextIf + AndNext + PauseIf chain, but it doesn't do that, per this screenshot:

Bizarrely, though, when I move the function one level lower in the call stack, it does create the chain as expected:

I've attached a version of the script that demonstrates the behavior.

If I just take the file you've provided and uncomment the && UnlessSavingAndQuitting() on line 39, I get the ResetNextIf you're expecting. Tested current master, 1.16.1, 1.16.0, and 1.15.2.
