wp-admin fails to honor style-sheet unless 'SCRIPT_DEBUG' is true.

[cjm51213]

Newly installed 6.6.2. Front-end requests worked fine. /wp-admin requests, by contrast, were css-free. For example, /wp-admin/wp-site-editor.php reported that javascript was not enabled and Firefox clearly showed that it was.

"define( 'SCRIPT_DEBUG', true );" was commented out in /wp-config.php. When I uncommented it, wp-admin began to behave normally.

I'm pretty sure that there is a defect and 'SCRIPT_DEBUG' compensates for it. My unfounded suspicion is that jQuery was not being loaded. 'SCRIPT_DEBUG' being on eliminated a wrong decision somewhere.
