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.
