Icon not displayed for some extensions in side panel

[sbatten]

Just noticed the current builds changed how the selected Tabbed Container UI option works. It is only displaying the Icon, not the Label anymore.

But, it is not working correctly for some extensions, like my Bookmarks and Project Manager, neither Microsoft's Live Share.

Is it something that will be fixed in the Side Panel itself, or extension developers must update their Side Bar icons to be visible there too?

BTW, the icons currently works perfectly in the original Side Bar.

Thank you
