Disable overscroll navigation when emulating touch.
When emulating another device in DevTools (including touch),
overscroll navigation is confusing for the user:
- if device does not support touch, user is not used
to the overscroll navigation and may be surprised;
- with content not filling the whole view, overscroll navigation
looks unnatural.
