Tiled video texture set to repeat safari vs chrome

When setting power of two video texture to repeat (gl.REPEAT) the texture will be clamped instead of repeating when tiled.
Also affects non-power of two video textures.

The video texture repeats correctly on Chrome and Firefox.

The issue has been encountered both on macOS and iOS.
Tested on:
MacBook PRO 16 2021 macOS Monterey (12.3) Safari 15.4
iPhone 12 mini (15.3.1)


Comparing examples between Safari and Chrome will show difference (video attached): 


Power of two example (modified mdn example - https://developer.mozilla.org/en-US/docs/Web/API/WebGL_API/Tutorial/Animating_textures_in_WebGL):
