Can't Exit or Interact in User Interface Tour

Opened the **User Interface Tour** via **Help** menu and since the left and right arrow keys don't work, I can't go forwards and backwards through the tour and there's no way to exit the tour either except by exiting the notebook. I noticed you have a fix committed for the left and right arrow keys so maybe it'll be fixed in that build. Just wanted to let you know.

Reproduce the User Interface Tour opened from the Help menu, checking whether the left and right arrow keys navigate and whether the tour can be exited without closing the notebook. Review the existing discussion and referenced fix, then consider the issue resolved when navigation and an exit path both work.
