I use html-minifier through grunt-contrib-htmlmin in a large project. Recently I observed that some existing code is breaking after minification:

<q r-center>
     <rf> ... </rf>
</q>

This is a html for my AngularJS application. The result of the minification is something like this:

<q r-center/>
<rf>..</rf>

Which is equivalent to this:

<q r-center></q>
<rf>..</rf>

Wich means the tag is pushed out from the Q tag. These tags are custom ones, there is no info regarding their type: block, inline, but the project does not need one. There are just tags.

Maybe this is an intended/normal behavior with this new version, and if so, I will need to get back to an earlier one or change the whole plugin.
