I'm having some major issues with the Speaker View feature in revealjs.

1. Changing the slides in the Main Window has no effect on the Speaker View Window
2. The Upcoming Slide is not updated

Here's a gif how the slides behave in my browser (first I activated the Main window, then the Speaker View Window. I've tested this on Firefox 105.0 (64-bit) and Chrome Version 105.0.5195.125 (Official Build) (64-bit). Is this a bug?
