New TitleBar control with PathIconSource as IconSource breaks the app

[Diegorro98]

Describe the bug

By using the new experimental control TitleBar, and using a PathIconSource as IconSource, the app breaks.
Other types of IconSource works, but PathIconSource doesn't.

Steps to reproduce the bug

<TitleBar
    Title="PathIconSource TitleBar">
    <TitleBar.IconSource>
        <PathIconSource

You can create an app and use the above code, or you can use the above code at WinUI 3 Gallery's Scratchpad but you will need:

1. cloning
2. checkout the branch feature/TitleBarExperiment
3. update to the latest Windows App SDK experimental NuGet package version (because at the moment I'm writing this, the current NuGet version is 1.6.240531000-experimental1)
4. build the app & run
5. Go to Scratchpad and paste the above code

Expected behavior

The app should run without problems and should display the path described at PathIconSource Path property.

Btw, I never posted the error logs, so here they are:

Because 1.7-exp1 is exactly the same version as 1.6-exp

The issue is still present at 1.7.250208002-preview1

(And I don't know if it is the same version as 1.6-exp too)
