these used to apply to a <cr-button> (a container that had a <papre-button>) but
now will apply to the <paper-button> itself, so my guess is this looks weird

The button has no content, so this really just applies to the button forcing a
new layout block, i.e. it doesn't mater whether or not there is an extra
wrapper. (The display: flex is the property that matters, without it it looks
weird). I'll leave any re-styling to whomever owns this now.

I see.... "display: flex" make the paper-button not take up the full width,
which I guess is valid if not ideal.

   margin-top: 20px;
 }
 
 #searchEnginesMenu {
   min-width: 150px;
 }
