When you make the file tree huge, scroll to the right, and then toggle it, stop it from growing

Summary: Depends on D19346. Ref PHI568. I love Javascript.

Test Plan:
  - 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.
