I am very disappointed with the behavior of the angular when it works in a DOM tree.
It inserts and parses directives directly in the HTML, but does not use documentFragment.
Why it can't make something like this?

Directive => inserting innerHTML into documentFragment => doing usual things with it => finding inner directives => parse them => repeat, until all directives into this fragment will be resolved => insert ready-to-use fragment into real tree.

I think, that must be a flag, because some peoples uses templateUrl without caching in production, so there will be a white screen for a log time.

Thanks!
