LPS-42455 - Button toolbar for a document in the DM portlet do not resize adequately based on portlet width or mobile screen width

Hey @Robert-Frampton,

Attached is an update for http://issues.liferay.com/browse/LPS-42455.  Nate said you wanted these reassigned to you to add in the flexbox changes.

Please let me know if you have any questions.  Thanks!
