- Viewed a revision.
- Dragged file tree view really wide.
- Scrolled document to the right.
- Toggled file tree off and on by pressing "f" twice.
- Before patch: file tree grew wider and wider after it was toggled.
- After patch: file tree stayed the same size after it was toggled.
- Dragged to various widths and reloaded to make sure the "sticky across reloads" behavior still works.
- Scrolled right, dragged the tree a bit, then reloaded and didn't see it flip out.
