When opening the popup to select the asset catalogs to show as tabs in the asset shelf, it's annoying that they would collapse back to the root level every time. This would mean users have to manually uncollapse a bunch of catalogs every time they call the popup. Since this is a popup, we don't need to be too careful about saving space. And in practice these catalog trees are usually rather small anyway. So simply uncollapse the first few levels of catalogs.
