Regression: Minimize/maximize/close broken by 1.0.1 runtime update with customized title bar

[fredemmott]

Describe the bug

I am using Microsoft::UI::Xaml::Window with ExtendsContentIntoTitleBar

This works fine but is a bit awkward with the 1.0.0 libraries.

With 1.0.1 runtime - no rebuild - they visually act as expected (hover/click color changes), but they don't minimize/maximize/close the window.

Steps to reproduce the bug

1. Get a clean windows install with no Windows App runtime
2. manually install windows app runtime 1.0.0
3. install MSIX from https://github.com/fredemmott/OpenKneeboard/releases/tag/v0.2.1
4. test minimize/maximize/close in that app (openkneeboard). They work fine.
5. close openkneeboard
6. install windows app runtime 1.0.1 update
7. launch open kneeboard
8. minimize/maximize/close still have visual effects on hover/click (color changes) but no longer minimize/maximize/close the app

Expected behavior

Minimize/close/maximize buttons should minimize/maximize/close the window with 1.0.1 runtime as they did in 1.0.0.

@bpulliam @pratikone please take a look

see if it is same issue as #6895 . Remove the right margin from titlebar element. it shifts the whole custom titlebar to left enough that caption buttons stop working. working to get the docs updated

[fredemmott]

I tried that; it fixed the buttons, but it also shifted the overall layout a bunch; after around an hour, I hadn't found a way to get both the buttons to work, and to have the content in the correct position.

Regardless, I don't think having to change the code should be the expectation/fix for compatibility with an automatically-installed .z update to a stable release

[pratikone]

yeah, we were fixing a few things. with new updates, it will ignore any margin (except for left margin). do try that out. I am closing this bug, if you continue to face any issue, feel free to open this up.
