Collection of InformationPanel issues

[mbklein]

I've been having a few issues with the InformationPanel. I wasn't sure how to break these issue up because it looks like some of them may be interrelated.

I have a manifest with 10 audio tracks, each of which has its own VTT annotations. My viewer configuration includes:

    informationPanel: {
      open: true,
      vtt: {
        autoScroll: { enabled: true, settings: { behavior: "smooth", block: "center" } },
      },
      renderAbout: false,
      renderAnnotation: true,
      renderToggle: true
    }

In other words: I have the info panel open, displaying only annotations, with no about tab.

In v2.4.0, this all works correctly – the annotations display on page load, and new annotations load/display when a new track is selected.

In v2.9.0 (the current release), the information panel does not display at all unless I set renderAbout: true, and the toggle button won't make it appear. This behavior was introduced in commit dbdf33d (included in v2.4.1).

Even with renderAbout: true, selecting a new track does not cause new annotations to load and display until I either click About and then return to Transcript, or click the Transcript tab on its own. This behavior was introduced in commit 69c6cf2 (included in v2.8.3-rc.0).
