Summary0001565: Regression from 2.2.*: Image not visible if clipped outside of screen with opacity less than 1
Description

An image in XAML isn't visible when following conditions are met:
1) its opacity is < 1
2) the parent canvas Clip height is such that canvas goes beyond screen bottom edge
3) image TranslateY is such that image's bottom edge is outside the screen

See attached minimal project to reproduce

Steps To Reproduce
  1. Open attached project, open SampleScene
  2. Run in editor -> all OK
  3. In CopyPastePage.xaml, uncomment line to change canvas opacity to 0.6 (from 1):
    <!-- ATTENTION: to reproduce image disappearing change opacity to < 1, like 0.6 -->
    <!-- <Canvas IsHitTestVisible="False" Visibility="Visible" x:Name="panelClone" Opacity="0.6"> -->
    <Canvas IsHitTestVisible="False" Visibility="Visible" x:Name="panelClone" Opacity="0.9">
  4. Run again
    Expected: all OK
    Actual: image disappears

This is a blocker for us, because we are working on a paint app and if the customer rotates their canvas to have one edge exit the screen, the whole image disappears.
