Auto merge of #19184 - bobthekingofegypt:fix/18706-abs-image-with-padding, r=mbrubeck

fix block size for absolute replaced element

Absolutely replaced elements with padding were incorrectly setting their
block size to include twice the padding values.  This attempts to stop
that extra padding for replaced elements but leave the working flow for
non replaced elements
