[WebGL]VideoPlayer Rendering stops when setting FilterMode of a texture downloaded with UnityWebRequestTexture.GetTexture()

--

-

How to reproduce:
1. Open the attached Project "webgl-video-atlas" and load Scene "SampleScene"
2. Build and Run the Project on WebGL
3. In the Player, Click the "Stream Video" Button
4. Observe the Player

Expected result: Textures appear to the right of the VideoPlayer and the VideoPlayer continues showing the video
Actual result: Textures appear and the VideoPlayer becomes black

Reproducible with: 2021.3.31f1, 2022.3.10f1, 2023.1.16f1, 2023.2.0a19, 2023.2.0b12, 2023.3.0a8
Not reproducible with: 2023.2.0a18

Reproduced on:
* Google Chrome 116.0.5845.187

* Safari 16.6 (18615.3.12.11.2)

* Mozilla Firefox 118.0.1

Did not reproduce on:
* MacOS Editor

* MacOS Player

Notes:
* The Audio of the Video continues playing and the frame counter keeps going up even with the VideoPlayer showing a black screen

* Firefox throws the following Warning into its Console:
"WebGL warning: drawElementsInstanced: TEXTURE_2D at unit 0 is incomplete: Bad mipmap dimension or format."

* The issue might not reproduce immediately on Firefox and might take a few tries

  1. Resolution Note (fix version 2023.3.0a14):

    The WebGL backend for the VideoPlayer was manipulating the graphics state directly from javascript without keeping the internal state cache (containing bindings) up to date. Now the internal state cache is correctly invalidated after the backend has updated the current frame from javascript.
