The first item (license) of the list on the right side of the metadata panel wasn't large enough (due to some recent global style change that I couldn't track down) and the top of the next item was visible. Added fixed height to prevent that. Also centered the credit/license text which looked sloppy. Bug: T101391 Change-Id: I848917ebb9c378c3210646486a87a6497d31a168
