Current behavior:

The tree view that sits within the index tab of the left-hand panel fails to show when the panel is expanded after being collapsed

Expected behavior:

The tree view should re-appear when the left-hand panel is expanded after a collapse

Steps to reproduce:

Using the this manifest as an example: https://api-beta.bl.uk/metadata/iiif/ark:/81055/vdc_100119049146.0x000002/manifest.json In 4.0.18 switch to the index tab then close the left hand panel and then reopen it. The tree view is missing

Related code:

this.extensionHost.subscribe(IIIFEvents.OPEN_LEFT_PANEL, () => {
      if (!this.$element.hasClass("loading")) {
        this.resize();
      }
    });

    this.extensionHost.subscribe(IIIFEvents.OPEN_RIGHT_PANEL, () => {
      if (!this.$element.hasClass("loading")) {
        this.resize();
      }
    });

Other information: The issue is in src\content-handlers\iiif\modules\uv-shared-module\BaseExtension.ts The css class loading is always present

I haven't tried to replicate this but if it's still there I guess it's a bug fix request?

I've tested the manifest specified above in both UV4 and UV3 in the demo instances on universalviewer.io. I tried this in both Chrome and Firefox on Windows 11 and saw the same results in both environments.

In UV3, the Contents area and the More Information areas are visible, but I can't see the actual audio player or hear the recording. [Link to the demo instance]

In UV4, the Contents area and therefore the hierarchical tree are not visible at all. The audio player loads immediately and the track can be played; the More Information area is present as well and can be opened and closed repeatedly. [Link to the demo instance]

Thanks, @sturkel89! Is it possible some rules have been changed recently that prevent the left panel from showing when there's only one component to the manifest, even if there's an index that should be displayed? Any ideas why the behavior might have changed between 4.0.18 and now, @edsilv?
