Consider merging https://chromium.googlesource.com/chromium/blink/+/486ed9f6fb9e9d72509c94a173092ac6370c35da The case of <track-list> without a <track-size> was properly handled but that's because style resolution had to account for the parsing being not totally right. This refactoring will help with implementing parsing for <repeat-function> as the code matches the specification more closely.
