get size after CSS

[Phil Race]

I'm not the authority on CSS, far from it, but so far as I know that's
just how the CSS works. So the node has no idea of the pending change.
I recall Richard saying a couple of months ago that SceneBuilder
has the same issue/need. I don't know if a solution was applied there.

Perhaps you could listen in on the style string property on the node
and when you detect its changed parse it yourself, looking for font and
size and directly apply the new font/size to a dummy Text object and
extract the needed info from that ?
