Just noticed that i accidentally removed a line. Readded it.

Conceptional the fix is quite simple.
Do all the changes which influence CSS before requesting the CSS state.

Basically fixes a half implementation which was done before.

Targeting the Release after makes of course sense!

Now after the JFX27 Release - it would be great if this PR can get reviewed.

Motivation for this was less the performance, but to ensure no temporary skin 
get's used, which can have side-effects on some implementations.

It's now `rfr`!
