GroupBox issue on flyout with the theme set to accent

[Tide]

I added a group box to the flyout demo for a flyout with a theme of Accent. What happens is you do not see the group box border on any of the accent colors except the default Blue. Here are some screenshots of Blue and Lime. I tried every accent color and this happens on them all except Blue.

Probably a coloring issue. I'll double check.

Sounds good thanks for all you guys do. This is a really nice project.

No problem. Anyway, this is a weird bug.

The GroupBox's border binds to AccentColorBrush but for some reason, it looks like HighlightColorBrush.

It is odd how it works when the accent color is blue but not on any other colors.

Indeed.
