JumpList doesn't update when opening a registered file using FileOpenPicker

Describe the bug

My app doesn't update the JumpList content (both in Start Menu and TaskBar) when opening a file using the FileOpenPicker. However, the Jump List is properly updated if I open the file (and my associated app) using a double click on the file icon.

Steps to reproduce the bug

Create a new app basen on Windows App SDK v1.5.4
replace the original Click event of the default button with:

private async void myButton_Click(object sender, RoutedEventArgs e)
{
    FileOpenPicker filePicker = new();
    var hwnd = WinRT.Interop.WindowNative.GetWindowHandle(this);
    WinRT.Interop.InitializeWithWindow.Initialize(filePicker, hwnd);

    filePicker.FileTypeFilter.Add(".lmest");
    var file = await filePicker.PickSingleFileAsync();
}

.lmest is my target extension

Register the extension lmest in Package.appxmanifest as below:
Compile and launch the app and try to open a .lmest file, then check the jumplist

Expected behavior

Expected JumpList:

jumplist

populated with the file you have opened through FileOpenPicker
