Click events get repeated on android

[Manishearth]

I'm not able to consistently reproduce this, but with a simple webpage with a click handler on a button, the click event sometimes gets triggered multiple times on android.

I think it depends on how you click it, but I'm not quite sure.

A tap will explicitly generate a click:

servo/support/android/apk/servoview/src/main/java/org/mozilla/servoview/ServoView.java

Line 294 in d7d9015

public boolean onSingleTapUp(MotionEvent e) {

Not sure if we are getting 2 taps or if it's something more convoluted.

Ah! Servo internally already has logic for converting touch events into click events. Adding support for touch events (#22229) broke this.

We simply need to remove any non-tap handlers.
