Thanks for the great v1.23 update. Our application imports a KML file with the position of a small fleet of ships. In addition to the icon (balloon) showing the position there is also a line that shows the projected sailing. All of a sudden, with v1.23 there is a misalignment of the icon and the origin of the line. The origin of the line seems correct, and it is therefore an icon offset bug, I believe.
For at least the past 7 releases of Cesium, there has been a precise alignment of the center of the icon with the origin of the line. It is a pretty convoluted system with dynamic czml import, menus/scripted popups, etc in a jquery-UI and Mobile framework, so there is always tension on compatibility on version upgrades, but everything has routinely worked fine. Until this.
The typical (actual) KML code in quesion is like the following:
Is there anything you need from me to illustrate it?
