Remote Debug Log of IOS HLS texture test failures.

Hi there, referencing this earlier ticket #163866 where HLS video textures was failing in IOS10 until FlipY was disabled with work arounds. It has become now apparent HLS video textures is failing completely since IOS 11 even with the CORS fix in place. This issue is still unresolved. 

This same problem of black frame rendering was apparant in IOS9 and so only IOS10 was working with the work around. 

I have produced some various tests including three.js , raw webgl with both mp4 and HLS streams to display the problem. No webgl flag addition / removal seems to fix it. 

I have investigated the webkit conformance test video texture files. It seems only mp4 was ever tested against Safari and it seems the tests were never designed for IOS as there is no user interaction code to begin the video. Therefore the IOS tests out of the box don't even begin. 

I don't believe these tests were ever done for IOS and most definitely HLS was never tested with webgl on IOS. 

I have had to modify the test files to include a HLS version of the mp4 video test files. All webgl tests fail and it will show the tiny canvas as a black frame at the top. I have made a heading where the gl canvas appears as a black square "Gl Canvas".  It will not render the texture.
