Bug 254207 – media/media-source/media-source-remove-readystate is a failure on GTK/WPE and media/media-source/media-source-monitor-playing-event.html timeouts on WPE

Test added in bug 254198 is a constant failure and I can't make much sense of it seeing that readyState calculations should occur in platform agnostic code.

The test calls `SourceBuffer.appendBuffer()` until there's over 10s of data added to the buffered range. Yet readyState stays at 1 (HAVE_METADATA)

The test found in `LayoutTests/media/media-source/media-source-monitor-playing-event.html` is incorrect too.

There's a sleep(1s) right after `sourceBuffer.remove(0, 10)` to check the `readyState` but it should have been updated even before the `updateend` event got fired.

I have marked it as failed for now.

The test media/media-source/media-source-monitor-playing-event.html passes fine on GTK now, but on WPE timeouts 90% of the times.
