[BUG] Media Element Seek not firing

Is there an existing issue for this?

Current Behavior

Media Element fails to seek playback positions under conditions where windows or android works fine. Examples include: -if using mediaElement.MediaOpened it will not fire under any situation. -if you are using StateChanged it will fire but only if you check its value before trying to seek.

I have no idea why the behavior in iOS is so different from Windows and Android? Is this intended to work this way? I have include3d sample repo showing what works does not work. Notes in app with what you have to do to make iOS seek.

Expected Behavior

Media element behavior should be the same across devices. Or please document differences for iOS.

Steps To Reproduce

1. Open included solution and run it.
2. Or create new maui solution and add media element package.
3. Add an event to seek an arbitrary position at start of video
4. Set event to fire when opening video.

Environment

- .NET MAUI CommunityToolkit: 3.1.0
- OS: iOS
- .NET MAUI: 7.0
Packages used:

 <ItemGroup>
	  <PackageReference Include="CommunityToolkit.Maui" Version="1.0.0-preview3840" />
	  <PackageReference Include="CommunityToolkit.Maui.MediaElement" Version="1.0.0-preview3840" />
	  <PackageReference Include="CommunityToolkit.MVVM" Version="8.1.0" />
</ItemGroup>

### Anything else?

In code there is commented out code that demonstrates a work around. Is media element behavior intended to be different across platforms? And if so can it be documented?

For Windows you might need to invoke it on the main thread, or I guess that is something we could add on our side.

That fixes it! Now I just have to rewrite the handling logic for playback position records so that I can take advantage of that. I have to either rework my app to do it using main thread or just use what currently works. ATM what I posed before works for what I need. I am currently tracking playback of video files across a list. And what I posed earlier does that and works on all device types. But your code works. Unfortunately I will have to rewrite my code to take advantage of it. My code is dependent on current behavior. I will rewrite it later if behavior changes.
