Graphics behind the transparent label backgrounds are not showing. #9001

Hello,

I figured out a rendering bug. If user adds label to map with transparent backgroundColor (like Color(0, 0, 0, 0.15) and sets showBackground to true, graphics behind the label are not showing but only world imagery.

Sandcastle example: Click to see.

Browser: Google Chrome 83.0.4103.116 & Internet Explorer 11.1282.17753.0

Operating System: Windows 10 Enterprise

What Actually Happens: Graphis behind the label are not showing.

Happen

Expected Behavior: User can see other graphics behind the label. For instance, graphics that behind a polygon are rendering as expected.

Expected

As @onderaltintas added:

You cannot pick labels easily and have to hit exactly on letters when you do background: false. Lowers user experience. If pick algorithm would be fixed for labels, no need to fix this one for me.
