Regression: #3932 breaks chaining of table_open markdown.it rules

[dwgray]

Describe the bug

I am using a markdown-it plugin to add classes to <table> tags. This was broken by #3932.

If you look at: https://github.com/vuejs/vitepress/pull/3932/files#diff-332834eb76757b8e31926e411cef34f7207564d0bf5fd00a185b41d97b3403bf

  md.renderer.rules.table_open = function (tokens, idx, options, env, self) {
    return '<table tabindex="0">\n'
  }

This breaks the chaining of any other modifications to the table_open rule. My understanding is that you should use the methods on token to modify the token and then chain to the existing rule. This post has a decent description: https://publishing-project.rivendellweb.net/customizing-markdown-it/#adding-classes-to-list-and-list-items

It looks like the overriding of math_blocks further down in the file does chain the original renderer.

Reproduction

In config.mts

import markdownItClass from '@toycode/markdown-it-class'
...
export default defineConfig({
...
  markdown: {
    config: (md) => {
      md.use(markdownItClass, {table: ['table', 'table-striped']})
    },
  },
})

Expected behavior

vitepress markdown.it plugin doesn't break other markdown.it plugin

#4082 should fix this 👀

#4082 should fix this 👀

Agreed - sorry, I looked at open issues, but I didn't think to look at open PRs.

It looks like this PR has been open through several releases, is there anything I can do to support getting this into the next release?
