I think the caption select icon in the overflow menu is set to "OFF" when it should be in "ON" mode.
When any subtitles track is selected the icon should be ON. Currently, icon says "captions are disabled" when they are not.
Look at Angel One demo:

The bug is in shaka-player/ui/text_selection.js:

 onCaptionStateChange_() {
    if (this.player.isTextTrackVisible()) {
      this.icon.textContent =
          shaka.ui.Enums.MaterialDesignIcons.CLOSED_CAPTIONS_OFF; // here should be CLOSED_CAPTIONS
      this.button.ariaPressed = 'true';
    } else {
      this.icon.textContent =
          shaka.ui.Enums.MaterialDesignIcons.CLOSED_CAPTIONS; // here should be CLOSED_CAPTIONS_OFF
      this.button.ariaPressed = 'false';
    }

    this.controls.dispatchEvent(
        new shaka.util.FakeEvent('captionselectionupdated'));
  }

@kartikeyshaurya, I assigned the issue to you. You should always feel free to work on PRs without waiting for assignment, though.
