Newline by `\n` does not give a newline in mermaid live

[richelbilderbeek]

Describe the bug

In mermaid one can use \n to create multiline texts:

flowchart TD

  test[No more\nnewlines?]

pasting that text in mermaid.live, however ...

flowchart TD

  test[No more\nnewlines?]

does not result in a multi-line-text, as shown in this screenshot:

To Reproduce Link to Live Editor: here Steps to reproduce the behavior:

Additional context

I'm a heavy mermaid user (yet with holidays), so I estimate this happened in the last two months.

I think in the same version, I noticed another bug: moderately long labels are now no longer rendered.

Example:

  X(This is a somewhat long label.)
