Scale effect direction not working

Scale effect direction not working

Hello! The 'direction' option for the 'scale' effect doesn't seem to work for me, so I tried it on the jQuery UI demo website and got the same results:


It just produces the regular scale effect as if no direction were applied.

My Chrome is Version 74.0.3729.169 (Official Build) (64-bit).
jQuery etc. is the one from the currently live demo website.

Can anybody else reproduce this?
