Description

This issue has been migrated from mozilla/webmaker-android#1819.

It was originally written by flukeout on Mon May 11 2015 and had the following description:

Neat little glitch:

  • Add an image and select it, release finger
  • Press and hold the delete element icon
  • With second finger, press and hold the image
  • Release first finger from delete button
  • Image will jump upwards, about 1/4 of the page height

Note - this also happens with the Edit Element & Add Element buttons.

Sooo... reason for this is that, technically, a touch event registers as "second finger was released", despite the fact that the "a second finger was placed" never got registered.

Contributor guide

Research direction
Investigate the touch event handling code for the delete and element selection interactions. Look for how touch events are registered and released, particularly for multi touch scenarios.
