Does not wrap in Handlebars templates

[gfoust]

This does not seem to be wrapping text in Handlebars templates (file extension .hbs). I am attempting to wrap the text in an HTML tag. For example:

<p>
  Some line that is long enough to require wrapping...
</p>

If I change the language mode to HTML then it wraps the line correctly, but if I change the language mode back to Handlebars then the "Rewrap Comment / Text" command does not seem to have any effect. I've tried both with a ruler and with a Wrapping Column value.
