Adding a HTTP link to a node description breaks the graph

I would like, to the graph below (also available via a JSFiddle)

<link href="https://cdnjs.cloudflare.com/ajax/libs/mermaid/7.0.0/mermaid.css" rel="stylesheet"/>
<script src="https://cdnjs.cloudflare.com/ajax/libs/mermaid/7.0.0/mermaid.js"></script>
<div class="mermaid">
  graph TD; 
  A[hello] 
  B[an <b>important</b> link] 
  A-->B
</div>

to add an actual link under link pointing to http://google.com.

I tried to modify the relevant node to

B[an <b>important</b> <a href="http://google.com">link</a>] 

but this breaks (crashes) the graph. Specifically, I noticed that what is not accepted is the href element.

Is it possible to add a link in a mermaid node?

Note: this report was initially asked as a question on SO but since other HTML tags are accepted it may rather be a bug.

This works (by using same http/https protocol as the page itself):

graph TD
Ready? -->|try this|B[click <a href=//github.com/knsv/mermaid/issues/467>here</a>!!]

See for yourself

Hey all. I got links working. questionA{"<a href='https://google.com'>Google link here</a>"}

setup was mermaid.initialize({startOnLoad: true, htmlLables: true}); This doesnt work on the live editor though.
