InputNumber on mobile works like textinput

[ x] bug report 

Current behavior
Chrome Android
When trying to write something in a InputNumber the full keyboard is open, also the validation that on desktop is working fine do not seem to apply on mobile.

Expected behavior
the input should have -> inputmode="decimal" (now i created a directive that add this attribute on input)
https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/inputmode
In this way on mobile the number keyboard will be shown.

The same validation logic like on desktop should run when user is entering values in input.

Minimal reproduction of the problem with instructions

try to fill inputs in this page android chrome

I was using inputNumber in my application and I came across a similar error even today. The mask works perfectly on the desktop, unlike on mobile, where the user can type periods and commas, breaking the model defined by the developer.
