Code Block without title creates syntax Atlassian does not render

[AMRoche]

Problem

When using the following render settings;

    codeBlock: {
      languageMap: 'javascript',
      options: {
        title: '',
      },
    },

, or anything that false coalesces (whitespace or null) the code block syntax output is as follows;

{code:title=|language=none|borderStyle=solid|theme=RDark|linenumbers=true|collapse=true}

and renders as

when submitted as comment content to JSM.

Suggestion / Identified fix

Replacing the "{code:title=|" section with "{code:" fixes the issue and renders as follows;

when submitted as comment content to JSM. As such, it seems like submitting a null value / unused property like that to Atlassian isn't supported.
