Any idea on when this might be included? Can anyone offer a temporary solution in the mean time?
Hi
I also suffered this problem. It may have been specific to me but this solution may help.
Open wp-admin/load-styles.css and look at the dubugging notice at the top of the page. I changed to ( E_ALL ) with no effect. Then added ( E_ALL | E_STRICT ). Refreshed site and the styles came back. Unfortunately I haven’t had time to research why this is but hopefully it can save you hours of hair pulling.
Thanks
