Setting Opacity to ProfilePicture incorrectly displays initials behind the picture

[0x5bfa]

Describe the bug

The above one is when Opacity is set to 0.5, the other one is when Opacity is the default value, 1.0.

Why is this important?

This issue is especially noticeable when it's used in TitleBar, which sets Opacity of Icon, Title, LeftHeader, RightHeader, etc. to 0.5.

See the "T" shown in the ProfilePicture in the screenshot, which shouldn't be the right visual.

Steps to reproduce the bug

<StackPanel VerticalAlignment="Center" Spacing="12">
    <PersonPicture
        Initials="TT"
        Opacity="0.5"
        ProfilePicture="/Assets/profilepic.jpg" />
    <PersonPicture Initials="TT" ProfilePicture="/Assets/profilepic.jpg" />
</StackPanel>

Actual behavior

As aforementioned.

Expected behavior

Initials should not be visible when the ProfilePicture.ProfilePicture prop is set
