I made a short video showing what happens when you disable that CSS rule. The thing looks a bit squished because I was trying to reduce the width of the window for the capture but at least I figured out a way to still use the plugin until a fix is implemented.
Everything worked perfectly fine before. The update seems to have locked the maximum size of the tree view CSS.
.height100, .tree-view {
/* height: calc(100vh - 250px); */
}
this is what messes it up.
and no, there are no files at top level. every share has folders within it, it's this CSS that was the issue
