The scope of the document does not change, only the text matched by the 
injected rules (i.e. the raw blocks) will show scopes from the injection 
grammar.

It shows the menu because the two actions have the exact some scope 
selectors.

A workaround would be to use a scope selector like: `text.html.markdown 
attr`.

Since we always have attributes in the scope, we’re matching a bit 
more than just the root scope, and thus will win over the default 
action, but it isn’t an ideal solution, right now though I can’t 
find of anything nicer.
