how to keep wp:preformatted default?

[wkingnet]

I noticed that Crayon changed the pre-formatted styles in wordpress.

Viewed using a code editor, the wp:preformatted block format is

<!-- wp:preformatted -->
<pre class="wp-block-preformatted">204.79.197.213 api.onedrive.com
23.76.75.24 api.onedrive.live.com
131.253.33.217 onedrive.live.com
131.253.33.217 webedgegeo.skyprod.akadns.net
131.253.14.230 skyapi.onedrive.live.com
134.170.104.157 skyweb.skyprod.akadns.net</pre>
<!-- /wp:preformatted -->

and Crayon code block format is

<!-- wp:urvanov-syntax-highlighter/code-block -->
<div class="wp-block-urvanov-syntax-highlighter-code-block"><pre class="lang:python decode:true ">
bs = BeautifulSoup(file_obj, 'lxml')
start = time.time()
for i in range(1000):
	bs.find_all(['a', 'img', 'link', 'script'])
print(f"time:{time.time() - start}")
# time:137.75350737571716</pre></div>
<!-- /wp:urvanov-syntax-highlighter/code-block -->

I think the problem is that both have the pre tag, but how to keep wp:preformatted default?

Yes, we have this problem now. You are right. It is because we use the same pre tag as it was in Crayon even before Gutenberg. I don't know how to fix it right now. I should somehow difference between pre for preformatted and pre form crayon in Gutenberg and use old logic for Classic Editor.
As workaround you can try to use
<pre class="crayon:false"
for preformatted blocks

But I will fix this problem later. I suffer from it too.
