TypeError: i.useStateStore().currentMultitagBuffer is undefined spam

Randomly (after unfocusing, changing window size, and changing tabs) I get this spam ^^. Not sure exactly what the best way to reproduce is.

#1900 changed a bunch of stuff in the client, and I noticed the multitag stuff seemed to work a lot better, so I'm going to say this is fixed unless someone else says something.
