Control bar doesn't auto-hide on history recording player

The control bar does not auto-hide on the history recording player. This was fixed in https://github.com/apache/guacamole-client/commit/2a2cef918945408da39372d8e3f2499e51528017, but has not been released as of yet.

The fix from the above commit should released in the 1.5.4 release, with the rest of the key event tracking changes left later for a non-bugfix release.
