WebGLTileLayer with palette style stops working after map.removeLayer/map.addLayer

[malaretv]

Describe the bug
WebGLTileLayers with a style that includes a palette seem to break when removed and added back to map.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://codesandbox.io/p/sandbox/cog-style-forked-2vg3p9?file=%2Findex.html%3A22%2C68 (A modified cog-style example w/ a button added to addLayer()/removeLayer() from map)
2. Click 'Add / Remove layer' button multiple times and see there is no problem.
3. Switch layer style to 'NDVI w/ palette 1'
4. Click 'Add / Remove layer' button multiple times and see there is now a black layer
5. Note in console warnings/errors (vary by browser) something along the lines of:
   WebGL warning: bindTexture: tex is from a different (or lost) WebGL context. or WebGL: INVALID_OPERATION: bindTexture: object does not belong to this context

Expected behavior
That the WebGLTileLayer shows with proper style when added back to map

Thanks for the report, @malaretv. I've proposed a fix in #15787.

Hope you're well.
