KNOWN BUGS

IMPORTANT:
- Page.on_enter called twice during page transition
- interpreter rendering gets garbled on scroll

NOT SO:
- transitions sometimes get confused when in fullscreen
- test_interpreter (first page) shows resizing issues
- indentation of list item content varies when list enumeration gets wide
- footer doesn't handle color changes
- interpreter focus when multiple in page (should follow mouse)
  focus should be in first on page, then follow mouse if it changes focus
