Description
When users set their preferred locale to something other than English, the link to the scene editor does not appear on the home page.

I suspect the same might be true for some of the other translations that are not part of the default translation files:

To Reproduce

Running the tabs default launch command (-t) does not respect redirects at the target.

$ node . -t https://aframe.io/a-painter

☝️ The above will error, even though the server will redirect to https://aframe.io/a-painter/ and serve HTML there:

$ curl -i https://aframe.io/a-painter

Noticed the right half of the keyboard works correctly for transparency during hover, but the left side keys show a black background on hover. The keys circled below are the ones tested as having this issue.
