Strange things happening using Sidebar from 'Invisible' state

Now that the Sidebars don’t entirely disappear, but instead reduce into icons, I’ve been trying to use them that way. Lots of strange things happen. If I Toggle the Sidebar to be visible, then use the same controls, it seems fine.

Eg. If I select a Hatch, then click on the minimized Properties icon in the Sidebar, the Object, Hatch, and User Text buttons appear stacked vertically and don’t work.

I’ve also noticed dropdown menus don’t work. And focus randomly shifts away when trying to enter text.
