[Segmented] Mouse over style does not follow SegmentedItem cornerradius

[HEIC-to-JPEG-Dev]

Describe the bug

Changing the corner radius of the SegmentedItem works when an item is selected, but when the mouse goes over an un-selected item it ignores the settings and shows a gray area using default settings

Steps to reproduce

<ct:Segmented SelectedIndex="1" HorizontalAlignment="Center" CornerRadius="18" Padding="4,4,16,4">
	<ct:SegmentedItem Content="Settings" CornerRadius="15" />
	<ct:SegmentedItem Content="Start" Margin="0,0,32,0" CornerRadius="15"/>
</ct:Segmented>

Expected behavior

Mouse over highlight should be the same shape as the selected items

Screenshots

As you can see, the white Start segmenteditem is how they should look, but the mouse over "Settings" is a different shape.
