On Android, Button.Released event does not fire in ContentView if placed inside a TableView and finger is released outside of the button [Bug]

[janne-hmp]

Description

I've made a custom image button using ContentView as follows (see the attached zip), see also CustomImageButton at:

https://github.com/hyvanmielenpelit/GnollHack/tree/master/win/win32/winclisrv/GnollHackClient/GnollHackClient/Controls

CustomImageButton.zip

It works fine otherwise, but on Android when I put it inside a TableView, Button.Release event does not fire if I drag the finger outside of the button before releasing. On iOS it works just fine, and also if I release the finger inside the button. Something to do with TableView on Android clearly.

Steps to Reproduce

1. Include the CustomImageButton custom control in your project or copy GnollHack repository
2. Put the CustomImageButton inside a TableView. In GnollHack, you can change UseVaryingBackgroundImages property on one of the buttons on AboutPage's table view to True.
3. Compile the project on Android.
4. Hold down the button (the image changes due to being pressed) and then drag your finger outside of the button and release. The image does not change back. If you do this and release the finger inside the button, it works.

Expected Behavior

On Android, CustomImageButton changes bitmap when the finger is released outside of the button.

Actual Behavior

On Android, CustomImageButton does not change the bitmap on released event if the finger was outside of the button. (iOS is ok, and also if the finger was inside the button when released, or if the button is not inside a TableView.)
