Is it intended that a global app style affecting Grid.RowSpacing affects Expander header+content spacing?

I'm migrating from XF 5.x to MAUI with .NET 9 and have noticed that some views no longer set default spacing (namely, Grid and StackLayout now have their respective spacing properties at 0 instead of what seems to have been 10 from my testing). To reduce effort from having to manually update every grid in XAML to set rows and column spacing back to 10 to maintain the look and feel of my app, I applied this spacing via a global style in a resource dictionary I load into App.xaml as a merged dictionary.

The side effect I've discovered of this is that the Expander, which internally uses a grid to render the header and collapsible content, is being subject to this global style. Is this intended? I can understand wanting community toolkit views to be as flexible as possible, but this feels like an oversight.

I forgout about this (thank you CoPilot for remembering), but I know I was using Styles + ApplyToDerivedTypes. Could you achieve the same using Global style, setting ApplyToDerivedTypes="False"?

Thanks for the help, but I ended up overriding row spacing where I needed it to be a non-zero value. My question was more if it was intended, not if there was a workaround :)

OK, maybe that's a question for @bijington ?

I would say no it isn't intended behaviour, I would expect the styling to require explicit overrides for the grid inside the control.

Is this something that should be filed as a bug report? Not a high priority since I have a workaround but it was unexpected during my MAUI upgrade from Xamarin.

If you could file it as a bug report that would be great. Thanks
