This is a duplicate of #10427.

The issue is not related to window behavior, but rather to the new TitleBar control (specifically the TitleBar icon).
As a temporary workaround, you can remove the built-in icon and manually add your own to the left content like this:

<TitleBar.LeftContent>
    <ImageIcon Source="/Assets/icon.png" Width="20" Margin="12,0,0,0" />
</TitleBar.LeftContent>

LeftContent

Does the TitleBar control have a LeftContent property?

LeftHeader

LeftContent

Does the TitleBar control have a LeftContent property?

Apologies, it was originally named LeftContent in WASDK 1.7 preview, but was renamed to LeftHeader in the stable release.
