Description (last modified by sabernhardt)

Running (Mac) Safari 13.1.2, WordPress 5.9, on multiple sites.

When loading the Customizer, I get a partial white screen – no left-column menu items (although the frame is there) and no page preview. Screenshot attached, and console error messages as follow:

I've tried disabling all plugins and switching to Twenty Twenty-two – no change in misbehavior. Misbehavior is confined to Safari, customizer works fine under Chrome and Firefox. :B
