Do checkbox grids automatically have the name 'RootGrid'?

[SirMixalotMixalot]

I was following the todo app tutorial and when it came to style selectors on the checkbox, the selector is
CheckBox:pointerover /template/ Grid#RootGrid and even in the visual tree of the devtools the grid underneath a checkbox has the name RootGrid

Here's my visual tree

Is this an issue on my part? A version difference? An issue with the tutorial?

In the tips, it tells you how to get the correct selector but I was wondering if the tutorial was now out of sync with the current version of avalonia or not.

It depends on the specific theme you are using.
For example, Fluent theme for ComboBox does have this "RootGrid" element: https://github.com/AvaloniaUI/Avalonia/blob/0cb1cf2990b7737de3bfe25494db6252012dbf93/src/Avalonia.Themes.Fluent/Controls/CheckBox.xaml#L30
