can you combine this?

  .controlled-setting-bubble-content[controlled-by='extension'] {
    background: no-repeat url(chrome://theme/IDR_CONTROLLED_SETTING_EXTENSION);
    background-size: 22px;
  }

-  min-height: 32px;
-}
-
-.controlled-setting-bubble-content[controlled-by='policy'] {
-  background-image: url('chrome://theme/IDR_CONTROLLED_SETTING_MANDATORY');
-}
-
-.controlled-setting-bubble-content[controlled-by='owner'] {
-  background-image: url('chrome://theme/IDR_CONTROLLED_SETTING_MANDATORY');
 }
 
 .controlled-setting-bubble-content[controlled-by='extension'] {
   background-image: url('chrome://theme/IDR_CONTROLLED_SETTING_EXTENSION');

^ why does this version of the bubble still get an icon in it?

It shouldn't. Brain failure. Thanks. That obviates the previous comment. I also
added another screenshot to the bug.
