With WebGL enabled on LibreWolf I get a black screen unless the browser is resized so that the canvas width and height are both 2048 or below. This issue does not happen on Firefox.
I get the below warnings in the console:
WebGL warning: renderbufferStorage(Multisample)?: Width or height exceeds maximum renderbuffer size. 3
WebGL warning: texStorage(Multisample)?: Requested size at this level is unsupported. 2
WebGL warning: blitFramebuffer: Framebuffer not complete. (status: 0x8cd6) COLOR_ATTACHMENT0: Attachment has no width or height.
WebGL warning: blitFramebuffer: Framebuffer must be complete.
WebGL warning: renderbufferStorage(Multisample)?: Width or height exceeds maximum renderbuffer size. 3
After reporting 32, no further warnings will be reported for this WebGL context.
Fine with width and height at 2048:

Black for any higher values:
