Additional marker/icon symbolizers are misplaced in 3D view

[allyoucanmap]

Description

Found in #9397 (review)

The additional marker and icon symbolizer are not correctly displaced because of the use of billboard.eyeOffset property (eg. as polyline start/end points). We introduced the eyeOffset property as a way to order multiple billboard applied to the same feature. Inside this comment #9362 (comment) there are other information about the use of eyeOffset including a link to a Cesium issue still open about to introduce the possibility to add a zIndex to entities.

We need to investigate and understand if it possible to replace eyeOffset or completely remove it because it seems it causing more problems rather than benefits

How to reproduce

additional-symbolizers-issue-3d.mp4

• create an line annotation in 3D on top of 3D feature
• add a style icon to the annotation line as starting point

Expected Result

The icon is visible at the correct location

Current Result

The icon is misplaced behind the feature

• Not browser related

@tdipisa
Unable to reproduce this issue anymore probably changes made as part of #9807 handled this case, as I don't see use of eyeOffset as zIndex

@allyoucanmap Could you please confirm. Thanks!

[allyoucanmap]

@dsuren1 yes, probably in that refactor for extrusion I removed completely the eyeOffset

Thank you @dsuren1 and @allyoucanmap. Moving to Test to verify again also with @ElenaGallo.
