Apparently, the mobile in-browser viewer (via Calibre Content Server) is not the same as the desktop in-browser viewer.
The desktop responds to mouse events,
but the mobile does not respond to touch events.
The touch events are recognized by other mobile ereaders, so clearly there is something in Calibre or Calibre Content Server that is problematic.
I described the problem, and attached a small video clip and a small ebook that demonstrates the problem in

@kovidgoyal, can you please take a look there and confirm my observation?
Thanks
