ItemsRepeater doesn't show items after maximizing window

[DmitriyYukhanov]

Describe the bug
When I have some items collection rendered using ItemsRepeater nested in ScrollView, and it's not visible due to being too low in the ScrollView, it does not render items after becoming visible when maximizing window.

If I do resize the window using window side handler, it does show up as expected.

To Reproduce

1. Run the attached repro project:
   Report.zip
2. Maximize window.
3. See no white rectangles appear at the bottom of the screen.
4. Now restore window and maximize it again.
5. See items are visible now.

Expected behavior
I expect to see items right away after first window maximize.

Desktop (please complete the following information):

• OS: Win 11 22H2
• Version 11.0.0-preview.4

Additional context
I'm using 125% UI scaling and 2K display.

Workaround is to specify MinItemWidth and MinItemHeight:

replace line
<UniformGridLayout ItemsJustification="SpaceEvenly"/>
with
<UniformGridLayout ItemsJustification="SpaceEvenly" MinItemWidth="500" MinItemHeight="500"/>
at MainWindow.axml to see items doesn't disappear anymore after maximizing the window.

I can reproduce the issue, but I don't have a solution yet for you.

Thanks for looking into this @timunie!
No worries, I'm happy to stick with MinItemWidth \ MinItemHeight workaround for now 😌
