Virtual keyboard issue on Android hosted Chrome

[a-bookkeeper]

Hello,

When I try to start the emulator on my Android hosted Chrome using the link http://www.scullinsteel.com/apple2/ I get the following issue:

At the same time, when I launch the emulator on my laptop, everything works fine:

I assume that it is possibly due to android security settings or something of this sort, but I don't have an expertise to solve the problem on my own.
It would be great to have a chance to play with the emulator on my Android phone on the go.

Please help.

Thank you.
