odd scenarios can trigger aframe-player tag to highjack focus

[btopro]

It's very difficult to replicate and isn't really related to HAX (but since it's an element we demo should figure out how to resolve) but some reason after a <a-frame> tag has made its way onto the DOM if your using hax and do the following:

• activate developer mode
• insert a layout that has a paragraph placeholder
• double click it (which escalates to paragraph
• click the paragraph and start typing
• now aframe has locked the page and scrolled back tot he top unless you hit esc. it's somehow gotten focus

Just a guess but I think this might fix it. https://github.com/aframevr/aframe/blob/master/docs/components/embedded.md

now doesn't even seem to work in latest version of chrome unless I'm missing something
