CollectionView does not shrink correctly on Windows

Description

As seen in the video below, if I expand the CollectionView and then shrink it back, elements that should appear at the edge of the screen are now off the screen (where they were when the window was stretched).

https://github.com/dotnet/maui/assets/338984/bc461cf9-c22f-486d-8d2c-114266f03724

I'm not sure how to test this type of scenario on the mobile platforms, so I'm not sure if this issue exists on those or not.

Steps to Reproduce

1. git clone [email protected]:jstedfast/Stocks
2. cd Stocks
3. git checkout -b collection-view-wobble origin/collection-view-wobble
4. git reset --hard 546edf8b84b0636e02ab6478fabbce139eb84e1b
5. Open the Stocks.sln in Visual Studio
6. Select "Windows machine" as the device
7. Build & Run
8. Stretch the window horizontally and then shrink it back to the size it started out and watch how elements that should be on the right-side edge of the screen are now out of view.

@jsuarezruiz - is this an actual dup and can be closed?

Verified this on Visual Studio Enterprise 17.8.0 Preview 1.0. This issue does not repro on Windows 11 .NET 8 with below Project: Stocks.zip

@XamlTest what version of maui did you use? I tested a basic app today with net8 p7 and it was still happening.

@mattleibow Sorry for the mistake, I verified with the wrong project branch before.

I verified again, the issue still repro on Windows 11 8.0.0-preview.7.8842. repo: Stocks(1).zip

Wanted to give a bump on this one and see if it's going to make it to GA

Could you try again with RC1?. Just tested with RC1 (and main branch) and cannot reproduce the issue.

@jsuarezruiz Verified again on 17.8.0 Preview 2.0 and 17.8.0 Preview 3.0 [34118.251.main] with 8.0.0-rc.1.23419.4, this issue still repro.

I downloaded the repro project from https://github.com/jstedfast/Stocks, collection-view-wobble branch.

I can also reproduce this on my project.

Based on the current milestone set it looks like this is not making GA, since this is currently assigned to '.NET 8 + Servicing'.

This is going to be a showstopper on updating to .NET 8 at least for me. I feel this is a fairly egregious user interface bug for Windows. Are there any known work arounds?

@samhouts what's the status of this issue? CollectionView is broken on Windows for months now!

[heribertolugo]

Also experiencing this issue. In my project the Header seems to work correctly, so this would tell me that the CollectionView itself is sizing correctly.

however, anything placed in ItemTemplate does not shrink with the window.

I am working with the latest MAUI and .NET at the time of this writing, and on Windows 11.
