Radio buttons active area overlaps

[Nils-Berghs]

Bug explanation

In WPF if you create a some radiobuttons in grid rows or in a vertical stack panel without vertical margins, the active area of the different buttons overlap.
This means that there is a region on the upper button that actually selects the next button (assuming that the upper button is declared first in xaml). When adjusting the Z index of the radio button it is possible to reverse it (i.e. part of the lower button selects the upper one).

<RadioButton Grid.Row="0" Content="Click my upper half to select me"/>
<RadioButton Grid.Row="1" Content="Click my upper half, or the bottom half of the button above, to select me"/>
<RadioButton Grid.Row="2" Content="Click me anywhere, or the bottom half of the button above, to select me"/>

Note that half is slightly exaggerated (maybe bottom third)

Version

@Nils-Berghs I tried to reproduce what you've described here, but I don't see the issue you're describing. Could you provide a sample repo/app that reproduces the issue?

@nicolaihenriksen when clicking on the text as in your sample, it works correctly, the problem occurs when clicking on the buttons itself

@Nils-Berghs Will try to reproduce it again...

UPDATE: Easily reproducible. I'll have a look at what's going on.
