Hi Team, Going through WPT failures, came across following WPT test case failing: Blink Commit: https://src.chromium.org/viewvc/blink?view=revision&revision=189185 WPT: https://wpt.fyi/results/html/semantics/embedded-content/media-elements/track/track-element/track-selection-metadata.html?label=experimental&label=master&aligned= Just raising so we can fix and align with spec. _____ This below compiles and progresses following test: void HTMLMediaElement::configureMetadataTextTrackGroup(const TrackGroup& group) { ASSERT(group.tracks.size()); // https://html.spec.whatwg.org/multipage/embedded-content.html#honor-user-preferences-for-automatic-text-track-selection // 3. If there are any text tracks in the media element's list of text tracks whose text track kind is // chapters or metadata that correspond to track elements with a default attribute set // whose text track mode is set to disabled, then set the text track mode of all such tracks to hidden. for (auto& textTrack : group.tracks) { if (textTrack->mode() != TextTrack::Mode::Disabled) continue; if (!textTrack->isDefault()) continue; textTrack->setMode(TextTrack::Mode::Hidden); } } _______ Just wanted to raise so we can fix it.
