Current behavior:

When loading a manifest using OSD extension the height of the tree view component isn't calculated correctly and the bottom disappears behind the footer because it overflows.

Expected behavior:

Component should be contained inside the left panel.

Steps to reproduce:

1. Go to https://journals.library.wales/view/1277425/1288658/111
2. Scroll down the contents pane and see that the last few items aren't visible

Other information:

Likely fix is to remove the JS-calculated height (set in the component class, passed to parent classes) and set height to 100% in css.
