Syntax Highlighter Block: Cannot format MATLAB code.

[vinnykaur]

Steps to reproduce

• Go to My Sites > Posts > Add new post
• Select Syntax highlighter block
• Add a code and choose MATLAB as the language from block settings.

What I expected

• It should ideally view the formatted code on publishing.

What happened instead

• The code isn't formatted.
• The code falls out of the margin.
• No line breaks between two syntax highlighter blocks.
• Tested this with Maywood/Twenty-Twenty/The Writer. I could see the issue on all the themes.

I believe we use a version of SyntaxHighlighter Evolved on WordPress.com. I tested the user's MATLAB example on Jurassic Ninja using that plugin and it caused an error:

On my test site the code wasn't formatted, but also didn't cause layout issues as in the screenshots above.

@mkaz I also tested your plugin and it worked as expected. Pinging you in case you have bandwidth to take a look at this issue given your expertise :)

The Evergreen team (formerly Guardians) is managing the SyntaxHighlighter plugin so they might be able to help with the errors.

With the regards to my plugin, I saw this raised in another channel and provided some info, but not sure the priority of switching out, or if anyone is working on it. @simison might know?

[...] but not sure the priority of switching out, or if anyone is working on it.

No plans as far as I know.

WordPress.com blocks are maintained by Grow focus tho, @lessbloat @obenland @creativecoder

Noting another complaint here:

This person is switching to C to see the code displayed properly.

Noting that I'm still able to replicate this issue. I've tested with Twenty-Twenty and Twenty-Twenty One themes.

@Automattic/evergreen Is this something you've come across before or could possibly help out with?

I put up a fix for it in Automattic/syntaxhighlighter#188. I think the WPCOM version has diverged a bit, but this is an easy change to make so once approved I'll fix it on WPCOM.
