Description
While working on PR #5066 for #5057 I noticed a potential issue when Page has both BackgroundColor and BackgroundImage set.
Steps to Reproduce
-
Set BackgroundColor="Red"
-
Set BackgroundImage="someimage.jpg" On all platforms, image is shown.
-
Set BackgroundColor=Color.Default iOS and UWP: image stays. This is because BackgroundImage is handled first before BackgroundColor, image takes priority over color. Android: image is gone, white background appears. Android doesn't handle the priority.
-
Set BackgroundColor="Red" iOS and UWP: image stays Android: background is Red
-
Set BackgroundImage=null iOS and UWP: Yay, background is finally red again! Android: Background is now white!
I attached a video with the described steps. pagebkgnd.zip
Expected Behavior
I'm not sure, I haven't been able to find it mentioned in the documentation portal what's expected to happen when both properties are set.
My proposal: like on iOS and UWP, have BackgroundImage take priority over BackgroundColor. When clearing the BackgroundImage, the Page should look with a background color of BackgroundColor.
Please let me know how you'd like this implemented, and I'd like to work on it
Actual Behavior
See it described in the steps above.
