Multipurpose modifiers quit working after a while

[joshgoebel]

Describe the bug or unexpected behavior

When using conditional modmaps the modifier can quit working because it gets confused if it's already pressed or not (preventing macros from firing when using a combo that includes the multipurpose modifier). Internally this has something to do with the key being treated as a modifier half the time and non-modifier the other half of the time.

Sample Config or Instructions to Reproduce

https://github.com/joshgoebel/keyszer/wiki/Hyper

My hyper setup PLUS adding a right-side hyper:

multipurpose_modmap("default",
    {Key.BACKSLASH: [Key.BACKSLASH, LHyper]  
})

Expected behavior

Should not get confused about whether key is pressed.
