Pressing the dot key on the NumPad does not apply the default decimal separator when the keyboard is set to EN-US/ UK. It always applies the dot.
Steps for Reproduction
1. Set the culture to a culture that uses the comma as a decimal separator - Italian.
2. Switch the keyboard to EN-US/UK.
3. Press the dot on the NumPad.
4. Validation prevents the input.
Dojo sample for reproduction:
jQuery version: 1.12.4
