LPS-44257 - Portal dockbar appears in two lines on mobile devices

Hey @pei-jung,

Attached is an update for http://issues.liferay.com/browse/LPS-44257.  Can we try to take a different approach at this issue?

I spoke with Rob, and we discussed about maybe making the flexbox apply only to the largest elements in the dockbar rather than trying to apply it to the entire dockbar because of the HTML markup of the dockbar and how it does not apply cleanly in its current state.  I think we can leverage some of the code here, but it seems very specific to our use case only.

Please let me or Rob know if you have any questions.  Thanks!
