Mike Kaganski e275726861 tdf#160593: make sure to use current element's font size for em unit
According to https://drafts.csswg.org/css-values-4/#font-relative-length
em is "equal to the computed value of the font-size property of the element
on which it is used". This means, that for an element that defines its own
font-size, attributes like 'dy' using em refer to the new font-size, not to
inherited font-size.
