A Bug

For some reason the menu is misaligned slightly to the left when using the body as a menuPortalTarget and setting the menuPlacement to auto, I'm not sure why this is the case and it only seems to happen in a specific layout (select on the right bottom), it seems like it could be adjusting for a potential scrollbar or something. When you hover over the items, the menu suddenly jumps to the correct position.

Thanks for your work on the library!
