wasm: mobile keyboard keeps popping on on android

The native mobile keyboard seems to pop up when the user clicks anywhere on the app, instead of just in an input area.

i.e. the inputmode=none does not seem to be working

To reproduce, qtbase/examples/widgets/layouts/basiclayouts example can be used. The mobile keyboard won't pop up if the click is on the app itself, but it will pop up if the click is below the app (grey area).
