It seems the previous faulty fill-extrusion-pattern/missing run is messing with the layer z-ordering in fill-extrusion-color/property-function.

I started digging into this and realized something extra weird was going on where only sometimes, and only (afaict) when using fill-extrusion-pattern layers, the extrusion texture was being bound without a depth buffer. This can happen with missing patterns (like in this case) or with valid patterns, with other layers or without — my best guess is that something in the ImageManager binding is interfering with the state. I haven't figured out exactly what it is yet, BUT since #9931 majorly overhauls the way create/use offscreen textures for extrusions, I tested several cases/platforms where I was reproducing this bug on that branch and it seems to fix them. 🤷‍♀️

That's great news @lbud!
