Chinese font glyph incorrectly rendered in MenuFlyout

[HO-COOH]

Describe the bug

Using this xaml

    <Button>
        关闭
        <Button.ContextFlyout>
            <MenuFlyout>
                <MenuFlyoutItem
                    FontSize="20"
                    FontWeight="Bold"
                    Text="关闭" />
            </MenuFlyout>
        </Button.ContextFlyout>
    </Button>

Produce a super weird “关” in the MenuFlyout, compared with what is correctly rendered in Button

Changing it to the same font size does not solves this issue.

It's just seems to me that they are using a different glyph rendering path.

Why is this important?

Because font rendering is essential to look.
