Multiple Entity codes in a row not supported in flowchart

[yoavst]

Description

For flowcharts, multiple Entity codes in a row (or entity code and then a non-space character) seems to work in normal strings, but not in markdown strings.

Steps to reproduce

Normal strings:

flowchart TD
  N1(["#lt;#116;"])

flowchart TD
  N1(["#lt;t"])

both produce the expected behavior of the text "<t"

markdown strings

flowchart TD
  N1(["`#lt;#116;`"])

flowchart TD
  N1(["`#lt;t`"])

both produce empty text for the node

Setup

• Mermaid version: 10.6.1 on mermaid.live
• Browser and Version: Chrome 120

I found the problem, in the SVG it render <t as html so it try to create new html element and not the text "<t".
I will fix this

[omer-priel]

The function markdownToHTML("<>") return <p><></p> and not <p>&lt;&gt;</p>.
And markdownToHTML("#lt;#gt;") return <p><></p> and not <p>&lt;&gt;</p>.

This happens because the fromMarkdown function (belonging to the mdast-util-from-markdown library) converts the < and #lt; to < and convert > and #gt; to >.

@aloisklink what should be the behavior according to mermaid?

PS, I'm asking you (@aloisklink) because, I don't know how to ask the team of mermaid contributors in GitHub
