** /overrightarrow symbol doesn't render**

Issue Summary

When I'm using mathjax for rendering, the /overrightarrow symbol doesn't render when $ wraps, but it renders fine when backslash wraps。I used the mathjax and katex.min.css plugins, and on the browser for the backend of the backsleven wrapped formula appears /[ and the formula has spaces so the formula cannot be rendered。i use vue-markdown to show mathjax

Technical details:

• MathJax Version: 3.2
• Client OS: (e.g.Windows)
• Browser: (e.g., Chrome )

I am using the following MathJax configuration: `

<script>
  window.MathJax = {
    tex: {
      inlineMath: [
        ["$", "$"],
        ["\(", "\)"],
      ], 
      displayMath: [
        ["$$", "$$"],
        ["\[", "\]"],
      ],
    },
    options: {
      skipHtmlTags: [
        "script",
        "noscript",
        "style",
        "textarea",
        "pre",
        "code",
        "a",
      ], 
      ignoreHtmlClass: "tex2jax_ignore",
      processHtmlClass: "tex2jax_process",
    },
  };
</script>
<script
  src="https://cdn.bootcdn.net/ajax/libs/mathjax/3.2.2/es5/tex-chtml.js"
  id="MathJax-script"
></script>`

I do not understand what this means. Can you explain the situation further?

Again, I am not sure what this means. Are you using MathJax and KaTeX together? (Both at once?) Spaces in formulas should not be a problem, so I'm not sure what issue you are referring to there. You seem to be concerned about the \[ delimiters. It is not the spaces that is the problem there, it is your configuration. You have used ["\[", "\]"] as one of your display math delimiters, but it should be ["\\[", "\\]"] because strings in javascript use \ as an escape character, so you need to double them to get a literal \ in the string. You have made your delimiters be just [ and ] rather than \[ and \]. The same is true for your inline \( and \) delimiters.

From your images: a red macro name in MathJax means the macro isn't defined. But \overrightarrow is defined in the base configuration, so I don't see why it would not be defined for you. You seem to indicate that this only occurs sometimes, and that it has something to do with wrapping, but it is hard to tell what you mean. Also, the image with the red macro names doesn't seem to correspond to the image of the LaTeX that you provide, so it is hard to tell where the issue is.

Is it possible to provide a link to a page that is exhibiting the issue?

If not, can you use the MathJax contextual menu to copy the original TeX notation on one of the expressions with the red \overrightarrow names and past that in here (not an image, but the actual text)?
