Description

The styles in packages/editor/src/editor-styles.scss are loaded after packages/block-library/src/editor.scss. I would expect them to be loaded before.

Because of the editor style wrapping that currently happens, style rules like ul become .editor-styles-wrapper ul, which has a specificity of 0-1-1, and so even a style rule in a core block's editor.scss like ul.has-background (which has the same specificity) will be overridden, because the default editor styles are applied after.

I discovered this issue while working on #21387, where I ran into the exact scenario described in the previous paragraph.

Expected behavior

The editor styles provided by the core blocks would be applied after the default editor styles, not before.
