Drawing arrows and coloring fields with a flipped board is broken

Question

Normal orientation works:

[FEN ""]
[StartPly "2"]

1. e4 {[%draw arrow,e2,e4,red][%draw full,e1,green]}

Flipping sides doesn't move the drawings:

[FEN ""]
[Startflipped "1"]
[StartPly "2"]

1. e4 {[%draw arrow,e2,e4,red][%draw full,e1,green]}
