This happens with a fullwidth panel which has plugins starting from left but not til the end of the panel. Even after the dialog is closed the border is there, until a new plugin is added or removed. Reproducible: Always
It was supposed to give an indication of the active panel (useful when there are multiple panels). Unfortunately it doesn't really work properly, so I have now removed it (rev. 20989). Thanks for the report.
