TileLayer Locking

Description

It seems that if you zoom/pan/interact with a TileLayer application for long enough, it locks. I haven’t been able to fully determine why this is happening - I think I notice that the requestScheduler eventually stops giving “priority” for new tiles to fetch, but maybe I was mis-reading that.

Repro Steps

Zoom/pan somewhat haphazardly/quickly for a minute or two on a TileLayer (which I recognize may be an abuse of the server, but I also have seen this happen much quicker than a minute or two). Maybe this is just an extreme edge-case, but I wanted to bring it up to see if there is a condition or something in the code that might be a known weak-point. I’m going to keep digging in the interim as well. I also recognize these are not great “Repro steps” but if people don’t think this is really an issue, I can also close this.
