Works like a charm on any of my recent WP projects. [EDIT]I need to change my review.
On some setups, I get two CSS editors shown in the «Custom CSS» attribute panel,
and only contents of the second instance are getting saved.Problem:Two CodeMirror
editors are displayed in the Custom CSS panel of the Blocks CSS plugin instead of
one. Both editors are located in the same container. Assumed Root Cause:WordPress
enables React StrictMode by default in the Block Editor. React StrictMode runs useEffect
hooks twice to detect potential side effects. Analysis:The Blocks CSS plugin initializes
CodeMirror in a useEffect hook.Since this useEffect doesn’t have a cleanup function
that checks whether CodeMirror is already initialized, wp.CodeMirror() is called
again on every mount cycle. With StrictMode enabled, this means: twice on the same
DOM element. Probable Solution:The useEffect hook should implement a cleanup function
that prevents CodeMirror from being initialized multiple times on the same element.
Side Notes:This only happens in some of my setups. I couldn’t figure out any possibly
conflicting theme, plugin or code snippet. So I assume it might be something like
a timing issue. Conclusion:I won’t change the 5-star rating, because despite of 
this problem the plugin does its job. And I know how to handle this issue by a simple
CSS rule to hide all Block CSS CodeMirrors except the last one:#o-css-editor .CodeMirror:
not(:last-child) { display: none;}

«Essential, Useful Tool, Completes the Block Editor, Should be part of the core,»
The one thing they don’t mention is how quick and genuinely concerned the support
is.

Can’t think of Block Editor without this. Tiny powerful thing. Only thing I hate
in this plugin is the following line: $render_css = empty( $file_name ) || strpos(
$file_name, ‘post-v2’ ) === false; This means if you deactivate Otter, your content
might just break 🙁
