can you make this an inline function? Or just put this in the header?

Make it a sentence please.

Do we have negative tests that are supposed to fail? If not, can you add them please?

Looking at it again, it looks like they are missing, since no test needs to be adapted. Please add negative tests as well, where the position is partly between background-position and -size, where you have 1, 2, 3, 4 or fife values. I just can see tests with 4 values. That is not enough. I assume we have tests for 1 and 2 values, but 3 and 5 are missing.

These on top were. Maybe it was not clear but after debug("background-position inside the background shorthand, some invalid cases, no changes expected"); in fact the style didn't change because the background values were incorrect. I made it more clear in the next version.
