The difference is compact mode. In compact mode it replaces the favicon, in normal/touch mode it adds an extra line with the "PLAYING" text.

If anyone knows how to turn this off, or prevent it moving the tab title up and down please let me know.

Pausing a video in one window then a second later having my attention drawn back to it by the movement is very annoying. I'm on xubuntu.
