fix(web): doModifierPress was testing against wrong device

The doModifierPress function was testing against the 'actual' device
rather than the virtual device, which meant that in the web debugger on
a desktop, testing a touch device, it was effectively testing against
the desktop device data rather than the simulated touch device data.

I did not observe any significant differences in behaviour between the
two modes. So I am not 100% confident that this change is necessary. But
it is a little concerning that there was a mismatch here.
