My concern here is neither of these actually fix the issue in a sustainable way. I’ve been playing with a way to modify and polyfill the global types to keep things reconciled but haven’t had a lot of time to dedicate to open source lately.

I have a version of this in progress on the fix-ts branch if you want to look at it to see if it fixes your issues. I'm working through how best to test this right now.

Tried to run the version on your branch, but ran into a TS error when trying to compile my project:

types.d.ts(23,26): error TS2304: Cannot find name 'CustomStateSet'

Didn't have time to investigate that much tbh, might just be on my end, but thought I'd share.

@lideen That makes sense. I've updated the file.
