Does not work correctly for macros.

[bvsn]

{% macro render_menu(model, style='b-menu_type_header') %}
    <ul class="b-menu {{ style }}">

Got next html:

<ul class="b-menub-menu_type_header">

It is also does not work if I put the variable into class tag.

A workaround: -- prepend {{ style }} with {{ " " }}.

This is not correct.

I think this is similar to issue 8 -- I've got a fork of this module over in https://github.com/eli-collins/jinja2-htmlcompress with a rewritten parser that should take care of this issue - it's a little less agressive / smarter about when it completely removes spaces.
