[BUG] MediaElement.Opacity doesn't work

Current Behavior

Hi, the Opacity property appears to be completely ignored on the MediaElement. The element's opacity cannot even fade when the opacity of the parent is changed... It remains at 100% until the element becomes not visible anymore (IsVisible = false).

Expected Behavior

The opacity should fade the element and the parent element opacity should fade a child MediaElement as well.

Steps To Reproduce

Create a new .net8 Maui project using available VS template. Install mentionned NuGet package. Add a MediaElement on the page or add it programatically... Add some video to the app folder. Wire the image source. After you have tested that the video loads correctly. Play with the opacity, you'll see right away that it doesn't work. Look at the repo for an example, but really it's 5 lines of code.

Anything else?

I suppose not many people need this, but I happen to need this. Any help is appreciated.

I just noted that for some reason, Opacity only apply on controls and not in Player, but yes, this is needed to make effects with multiple media/channels

Looks like this could be done here: #1891

@vhugogarcia this is being discussed as a proposal to add support for texture view.

Thanks @ne0rrmatrix for pointing out. Thanks @olographio for reporting the issue, however, this is not an issue but rather a new feature request which is actually being discussed on this issue: #1891

I'm closing this issue, so we all can follow-up there.
