ImageEx in ListView freezes UIThread

uwp-community-toolkit version2.2

I've got a couple of ImageEx element inside my listview which they are bind to urls. So when I launch my application it seems like UI thread is blocked by ImageEx. I cannot move app window, resize window, scroll the list or interact with another part of the application till all the ImageEx images are loaded from the Internet.

I wanna know if this is the normal behavior or not?! And if there is a way to fix the problem?!

My ListViewItem Template:

<DataTemplate x:DataType="m:RepoModel">
   <controls:ImageEx x:Phase="3"
        IsCacheEnabled="True"
        Source="{x:Bind owner.avatar_url}"
        Height="125" Width="125"                                       
        PlaceholderSource="ms-appx:///Assets/pl.png"/>

Solution

As Shawn Kendrot mentioned, they have fixed it on uwp-community-toolkit version3.0 and I just test the stable version and I can approve that
