Spacing of some controls affected when `<group>`-ed

[justparking]

Shown here grouped:

        <group>
          <subtitle>Speakers</subtitle>
          <button join="DSP Speaker1-On" arg-on="true" arg-off="false">Speaker 1</button>
          <range join="DSP Speaker1-Fader" min="-50" max="0" showevent="DSP Speaker1-On"/>
          <meter event="DSP Speaker1-Meter" range="db" type="horizontal" showevent="DSP Speaker1-On"/>
        </group>

vs Ungrouped:

          <subtitle>Speakers</subtitle>
          <button join="DSP Speaker1-On" arg-on="true" arg-off="false">Speaker 1</button>
          <range join="DSP Speaker1-Fader" min="-50" max="0" showevent="DSP Speaker1-On"/>
          <meter event="DSP Speaker1-Meter" range="db" type="horizontal" showevent="DSP Speaker1-On"/>

This still seems to fail with nested groups, e.g.

<row>
  <column sm="3">
    <group>
      <subtitle>Speakers</subtitle>
      <button join="DSP Speaker1-On" arg-on="true" arg-off="false">Speaker 1</button>
      <range join="DSP Speaker1-Fader" min="-50" max="0" />
      <meter event="DSP Speaker1-Meter" range="db" type="horizontal" />
    </group>

    <group>
      <title>Group within a group</title>
      <group>
        <subtitle>Speakers</subtitle>
        <button join="DSP Speaker1-On" arg-on="true" arg-off="false">Speaker 1</button>
        <range join="DSP Speaker1-Fader" min="-50" max="0" />
        <meter event="DSP Speaker1-Meter" range="db" type="horizontal" />
      </group>
    </group>
  </column>
</row>

It seems we missed nested .well's. This can probably be fixed by removing the direct child selector:

.well {
