When I open a file and move its tab to float it, it appears floating with half of the window filled with the Symbols, Projects, Class, Defs, and Open tools pinned. When I unpin to hide them, they move to the left to show the file, but sometimes the tabs on the bottom and the original scroll bar fail to disappear (see attached picture).
This only happens when I grab the tab and move it out of the editor window. If I double click the tab, the window displays correctly.
