Firefox Canvas Size Errors

When you edit HTML on Firefox, the ace editor won't detect that you're shrinking/growing the canvas and wordwrap too early.

Reproduce the issue in Firefox by editing HTML and shrinking or growing the canvas while observing the Ace editor's word wrapping. Trace the canvas resize and word-wrap handling from the browser-facing editor entry points; done means the editor detects the new size and wraps at the correct width.
