On wikis where certain "topicons" are moved out of the mw-content-text wrapper into the root of #content the VisualEditor toolbar shows a weird blank space.
The icons in question are invisible due to float overlap, but they do push down the toolbar and occupying space to the right of the "Save and review" button thus pushing it and the rest of ve-ui-toolbar-actions to the left.
To reproduce this situation, run the following one or more times:
$('#content').prepend( '<div class="mw-topicon" style="display: block; width: 20px; height: 20px; background: pink; float: right; margin-left: 3px;">x</div>' );
Version: unspecified
Severity: normal
