Issue #1014 - Replay doesn't work after seeking to duration
Issue #1014 - Replay doesn't work after seeking to duration

Browser behaviour for when you seek to duration differs between
each browser but it appears that seeking just before duration
behaves the same regardless to browser.

When seeking, can check if we are seeking to the video's
duration and if so, push the time back a little.

Closes #1014
