Issue descriptionUserAgent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:63.0) Gecko/20100101 Firefox/63.0 Steps to reproduce the problem: 1. Use h264-encoder (https://github.com/xevokk/h264-converter/tree/6d8477482be5d8c0ec9163de144504f33a00293d) to play a 6MBps h264 video stream via MSE. 2. Allow to play What is the expected behavior? Same as in firefox: no error is thrown and the SourceBuffer is rotated (ie. earlier fragments are removed from the buffer). So the video continuously plays fine. What went wrong? After about 20seconds a QuotaExceededError is thrown Did this work before? N/A Does this work in other browsers? Yes Chrome version: 70.0.3538.102 Channel: stable OS Version: 16.04 Flash Version: Shockwave Flash 31.0 r0 I asked about this issue here on stackoverflow with some response: https://stackoverflow.com/questions/53309874/sourcebuffer-removestart-end-removes-whole-buffered-timerange-how-to-handle/53364228?noredirect=1#comment93606478_53364228 I wonder if this is similar to https://bugs.chromium.org/p/chromium/issues/detail?id=563292
