I believe I found the issue. at Files.App\Helpers\Navigation\NavigationHelpers.cs inside the UpdateTabInfoAsync method there is this bit of code. I did not add this comment and I am not familiar enough with the project to understand exactly how a1 and a2 are checking if the contents of the tab have changed. However, it is keeping the tab from initially loading the header, icon and tooltip.

If someone more familiar with how this works would like to advise me, I'd be happy to fix it. Otherwise feel free to just fix it if that's faster/easier for you :)

// Don't update tabItem if the contents of the tab have already changed
if (result.Item1 is not null)
{
    var navigationParameter = tabItem.NavigationParameter.NavigationParameter;
    var a1 = navigationParameter is PaneNavigationArguments pna1 ? pna1 : new PaneNavigationArguments() { LeftPaneNavPathParam = navigationParameter as string };
    var a2 = navigationArg is PaneNavigationArguments pna2 ? pna2 : new PaneNavigationArguments() { LeftPaneNavPathParam = navigationArg as string };

    if (a1 == a2)
        (tabItem.Header, tabItem.IconSource, tabItem.ToolTipText) = result;
}

That code is for #12939. It used to work fine, so the recent changes must have prevented it from working properly.

I submitted a PR to fix this issue. #15898 @MrFrawsty thank you for the information!
