Thanks for testing. I was using Chrome on Android 8.0. Interestingly 
enough, it does not happen for me when I turn on Chrome's "desktop mode" 
but still select Horde's "Mobile (Smartphone/Tablet)" mode on the login 
screen. However, Chrome's "desktop mode" is not a real workaround 
because everything is displayed too small to be usable on a smartphone 
even with Horde's "Mobile (Smartphone/Tablet)" mode turned on.

Same thing BTW using Chrome 61.
