Media Tiles do not zoom Full Screen on some screen sizes or browsers (as of v6.10.0)

Prior to v6.10.0, Media Tiles would zoom to somewhat fill the window (the screen), but now may only zoom a smaller extent and leave substantial margins / blank padding - depending on the screen or window size.

This behavior has been confirmed and is bug/side-effect of performance optimizations made to Media Tiles as a part of Release v6.10.0.  We are researching to determine the root cause and possible solutions.
