Filesystem watcher glob pattern help

I can’t seem to get the glob pattern for to work with negated patterns or multiple combined patterns. It only seems to work when it’s a single positive pattern.

I don’t see a way that I can look into the function to see why the glob pattern isn’t working. I just have to do trial and error with different patterns to see what works.

I’m trying to negation with !, and combined patterns by surrounding in parentheses and separating by |

Is it supposed to be possible to do negation and combined patterns with Or is this an intended limitation?
