That's using an <img>, for which the bitmap it generates DOES NOT DEPEND 
ON THE STYLES.

What we are discussing is your proposal that for an <svg> element the 
generated bitmap depend on styles, but on some totally different set of 
styles from the ones the element actually has assigned... and that this 
totally different set only be used in situations when the element 
happens to have certain "real" styles.  Is that a fair summary of your 
proposal?
