Indeed very weird. Don't have an explanation for it either, sorry.
Developing HTML email really sucks. Next to funky email servers we also have to take into account that pretty much all modern CSS is unsupported and that clients have many things disabled by default.
Quite often I think it is not worth it at all. Other than links, text only is the way to go. Unfortunately clients think differently.
