[Android] Animation on Opacity Issue

[Stedy59]

Description

If you perform an animation on a controls Opacity property, the maximum value will be the value when the control was created.

For instance, I have a control the starts out at Opacity=0.5, the animation sets the Opacity value to 1.0, but the Opacity range is now set to 0=>.5, so setting it to 1.0 means an actual Opacity of .5.

In the example below. five controls are created with opacity values of 1.0, .75, .50, .25, and 0.0.

The first button animates each to an opacity of 0.0, the second to an opacity of 1.0. You can see the Opacity value on the right go from 0 to 1, but the actual opacity is capped at its initial value.

This works fine on Windows... and I haven't tested to see if other properties are effected.

Steps to Reproduce

Problem: If I have two layered controls on a form and set a click event to fade one in and out, the control that starts off with opacity=0 will never show....

Expected outcome: Opacity works correctly.
