Options for katex-plugin not possible

[smartnio]

Describe the issue

Hi,
i just wanna know how to set options for the katex-plugin within the md-editor-v3 config. I followed the docs with configurating the markdownItPlugins section in the README. But i can't figure out, how to change options for the katex plugin, because the katex options is a vue reactive katexRef which is not available on configuration start.

I want to set e.g. the strict mode of the plugin to get rid of warnings. They are inside p.options.katexRef.value.SETTINGS_SCHEMA

config({
  markdownItPlugins(plugins) {
    return plugins.map((p) => {
      if (p.type === 'katex') {
          //not available on startup
          //stores a ref
          console.log(p.options.katexRef)
          //undefined
          console.log(p.options.katexRef.value)      
          
          //available, but of course, not settable after configuration is already initiated
        setTimeout(() => {
          //filled with SETTINGS_SCHEMA
          console.log(p.options.katexRef.value)
        }, 2000)
      }
    })
  }
});

If not an issue, can be moved to discussion. But thanks for the help!

When using CDN, we cannot obtain an instance of katex here, and it's currently not possible to get it here either. I will try to enhance it later.

Currently, installing via dependencies works:

npm i katex

import { config } from 'md-editor-v3';
import katex from 'katex';

config({
  markdownItPlugins(plugins, { editorId }) {
    return plugins.map((item) => {
      if (item.type === 'katex') {
        // will not be undefined
        console.log('katexRef', item.options.katexRef.value);
      }

      return item;
    });
  },
  editorExtensions: {
    katex: {
        instance: katex
    }
  }
})

4.19.0中优化了这个问题，参考https://imzbf.github.io/md-editor-v3/zh-CN/docs#%F0%9F%94%A7%20katexConfig
