I followed those instructions. Did I make a mistake?

I don't think so, it's mostly for future readers.
This being said, I think the team prefers to do the dependencies updates themselves.

[multimeric]

Fair enough, but I would love if this started a discussion on bumping the version as the current one is fairly old. I'm after a mermaid fix which I can't really get without updating it here.

Isn't it what #13600 is/was for?

As you may know, you can't update all dependencies too frequently.
You see the lacking features from Mermaid.js but you omit the big picture which is Mermaid.js has to play nicely with all the other dependencies such as Reveal.js, code-annotations, etc. There are already JavaScript conflicts (in particular with Reveal.js) and those are very hard to catch with tests.

Anyhow thanks for the interest and the PR, the team will decide based on the current priorities and workload, if this update should happen "now" or later.

We haven't yet done the update for 1.9. Last one was #12939 for v1.8

This seems ok to me but I'll defer to @cscheid for merging this, as he is the one usually doing this update.

Thanks so much, @multimeric ! We should be able to take this in. Have you verified that the basic functionality works?

We can't really do good automated testing here because it's all visual and image snapshots rot pretty much instantly.

I'm just asking so that we have your answer, and then if someone else reports a failure, we'll ask you again before reverting ;)

Thanks again, we do truly appreciate the help!

[multimeric]

I understand that comprehensively verifying the functionality could be difficult. I can confirm that it at least works for my motivating error case.

I'm ready to merge this, but I'll wait for your changelog edit just so we can make sure you get credit. Thanks again!
