--- Comment #8 from Kyle Piddington <kpiddington at apple.com> ---
Contrast this with the OpenGL backend, which has no support for EXT_Color_buffer_float, so OIT.js line 28 (const extensionsSupported = context.colorBufferFloat && context.depthTexture;) returns false. _translucentMRTSupport, and _translucentMultipassSupport will both be false, so we never create a render pass that requests blending.

I suggest also adding context.floatBlend to the list of extensions required for OIT.
