I can confirm that both plugins (and their respective block types) can now be used next to each other when using the Gutenberg editor.
Thank you very much for the lightning-fast fix!
Great! Thanks for the quick response. I opened a new topic on katex’s site.
Unfortunately, WP doesn’t give me any errors. All I can find is from web-console:
SyntaxError: redeclaration of const registerBlockType
for file blocks-highlight.js:1:1
Does that help?
