[Firefox Android] Examples materials / video and video / panorama / equirectangular broken

I’m not exactly sure if this ever worked or when it started breaking, but video textures seem to have errors on Firefox for Android. Below is the GL error / warnings spit out by Firefox Dev Console:

And the result is that the material returns black to the fragment shader.

I’ve tested these web pages on Firefox for Android with the error described above:

• https://threejs.org/examples/webgl_materials_video.html
• https://threejs.org/examples/webgl_video_panorama_equirectangular.html

I will cross-post this with Firefox as it may be a GL error on the vendor’s side. (Updated: Ticket)
