Release InputEvent event doesn't match with move event on Android

[ricochet1k]

Godot version:

3.2 branch after rc4: 6b5102c
Also happens on 3.2.3.rc4

OS/device including version:

Android Pixel 2, GLES3

Issue description:

The position of the touch release event on Android doesn't match the last motion event, but only for swipes that move left, or up. Right and down swipes work fine.

It seems related to the code to adjust input events based on the control's position, without the white rectangle above this doesn't happen.

Steps to reproduce:
Export the repro project to an android device. Touch the screen, drag to the left, let go. Blue square should be centered in the green square, but you'll see that it is offset downwards by the same height as the white rectangle. (there is a white rectangle at the top of the screen, it's hard to see because it blends in with the page.) Red is the touch down event, green is the last move event, blue is the touch up event.

Strangly, swipes to the right work as expected:

Minimal reproduction project:

Also related: Trying to isolate this further into whether it's mouse or touch events, I find that InputEventScreenTouch is never sent with pressed == false, so there is no event for touch release.

I have tried to replicate this problem in v4.0.beta.custom_build [e82d66f] but this issue is no longer reproducible. Can't say anything about v3.x.
