Patch by DieBuche, who explains the CSS:

    If the image height is lower than the line-height, the margin-top
    is applied to the top of the line.  a very short image will not
    follow for 3-4px laters, thus leading to a bigger distance from
    the top than it should be.  vertical-align:text-top moves the
    picture up, so this problem doesn't happen

I've not tested this, but DieBuche and Derk-Jan Hartman tested and
provided screenshots in the bug.
