Does not support cursor movements from the ios keyboard

The arrows above the keyboard work fine, however force touch dragging on the default keyboard usually moves the cursor in standard text fields and it does not on blink

No files or tests are named. Reproduce the issue in Blink using force-touch dragging on the default iOS keyboard, compare it with standard text fields, and trace the text-input entry point involved. Done means force-touch cursor movement works in Blink as it does in standard iOS text fields.
