React apps may crash when "Link External iframes" is active.

I noticed that the crossword on Puzzmo throws an error if the Gamepad Navigator is installed. I can consistently get the page to load again if I uninstall the extension.

It doesn't happen with any other of the puzzles there except the "I'm Done" button in the "SpellTower" game.

I suspect it's because we put our content at the end of the body, and that we might avoid these issues by prepending our elements instead.

Moving the element to the beginning of the body made no difference. Removing the elements manually using the dev console also didn't help. I'll need to do some searching.

This seems to be a common problem when working with some React apps while extensions are loaded.

Turning off the "Link External iFrames" setting resolves the issue.
