Anchors for headers with HTML

[winniehell]

Using aglio 2.0.4 with olio 1.2.1, the following

# Group <strong>Important</strong> Stuff

## Bar <span class="badge"><i class="fa fa-plane"></i></span>

leads to the following HTML

<section id="strong-important-strong-stuff" class="resource-group">
  <h2 class="group-heading"><strong>Important</strong> Stuff
    <a href="#strong-important-strong-stuff" class="permalink">¶</a>
  </h2>
  <h2 id="header-bar-span-class-badge-i-class-fa-fa-plane-i-span-">Bar 
    <span class="badge"><i class="fa fa-plane"></i></span> 
    <a class="permalink" href="#header-bar-span-class-badge-i-class-fa-fa-plane-i-span-" aria-hidden="true">¶</a>
  </h2>
</section>

Though the generated anchors are straight forward, the following seems more natural to me:

<section id="important-stuff" class="resource-group">
  <h2 class="group-heading"><strong>Important</strong> Stuff
    <a href="#important-stuff" class="permalink">¶</a>
  </h2>
  <h2 id="header-bar">Bar 
    <span class="badge"><i class="fa fa-plane"></i></span> 
    <a class="permalink" href="#header-bar" aria-hidden="true">¶</a>
  </h2>
</section>

so that you can refer to Important Stuff by #important-stuff and to Bar by #header-bar

In my opinion HTML tags and their attributes should be ignored when generating anchors.

The special case that content of HTML tags should not occur in the anchors either like in the following, can wait for special syntax in my opinion:

## <i class="material-icons">settings_input_component</i> Settings

There is a CommonMark discussion about HTML attributes in Markdown and kramdown already supports it.
