I have only encountered this when an element is not 'displayed'. There are many things that may make an element not displayed. It sounds like you have checked most of them. Are you 100% certain that this polygon is being rendered? Like change it's fill and see if it changes on screen?
It has fill="none" .. because I don't want the box to be visible. I'll try changing it temporarily to see if that helps...
Fill none should still work (as it may be sensitive to pointer events). I would still try just toggling the fill because that will make sure that you aren't missing something in the document.
But this brings up the question, what would be the "right" way to have a graphical element not visible but "rendered enough" to have a bounding box?
visibility=hidden should also work (for the same reason above).
In this application, each room on a map has a polygon defined. When we want to fill in the room with a certain color, we set the fill attribute accordingly. But also, we'd like to be able to compute the "center" of the room somehow, and our strategy was to find the bounding box of the room's polygon and use the center of that as a close approximation. We need to compute the centers of the rooms when the map is loaded and before any rooms are filled in.
