@nicolasbrugneaux - Thanks for the PR, there was a typo that stopped this from actually working. Once fixed, there was then the problem that $sce was kicking in and complaining that this had unsafe HTML and so was throwing a security exception rather than displaying the HTML.

You can test this stuff yourself by running:

grunt package webserver

Then browsing to http://localhost:8000/build/docs

You can also check the e2e tests by running

grunt test
