Template fullscreen not resizing text area
Full screen button in template editor window works, but text field does not resize (same number of lines displayed as when it is the smaller window).
Workaround - Once full screened, click between "Diff" and "Preview", then back to "Input". This causes the window (and subsequently the text field to redraw itself. This fixes the issue until the page is reloaded (even when switching between fullscreen and regular multiple times).
