The admin styles seem to specifically target the body. Could we move these particular styles out of the here(.editor-styles-wrapper) block and under body, maybe with a link to which styles are being reset?

Also when did this break? Where you able to pinpoint the specific commit or release?

The selector needs at least 0-0-1 specificity to override body, which it had before removing html in 46752.

I made #61959 to restore that selector exactly as it was for the whole set, and Aaron already suggested to isolate the change to only the first selector of the stylesheet.

In that case, we should probably change the selector to:

div:where(.editor-styles-wrapper),
body:where(.editor-styles-wrapper)

So that it overrides the admin styles for both an iframed and non-iframe editor.

html :where(.editor-styles-wrapper) applied to either element in WordPress 6.3, and I just made a quick edit directly in wp-includes\css\dist\block-library\reset.css with 6.6 beta to confirm that it still covers both elements.

iframe:

iframe editor with corrected background and font size

non-iframe:

non-framed editor with element inspector open

(the theme for these screenshots is Twenty Thirteen)

Why not just restore it to https://github.com/WordPress/gutenberg/pull/46752/files#diff-bda8e417e9cfc8724167f4c82aab1d0d205245c51360a8afa4bba99ba078e6dbR10?

Restoring is what I tried first :) #61959

Yes, so we only want it to affect the top level styles. I guess I meant, why not take out that section and do it in a separate block? I find that a bit more readable than html &.
