The reveal answer button accidentally loads files into the embedded
editor that aren't properly relativized. This ends up switching the
currently open file to a different file, unexpectedly.
In addition, due to the incorrect paths, files like `favicon.ico` end up
being loaded in the embedded editor; resulting in a bad experience as
the images are shown as plain text.

To increase the ease of development we are moving @angular/docs into the adev directory within this repo. While
we are doing this to improve our development experience in the short term, efforts are also in place
to maintain a division between this @angular/docs (shared) code and adev itself, so that it can be extracted
back out in the future when components is ready to leverage it as well.
