markdown.extractHeaders config option does not work

[Otto-J]

• I confirm that this is an issue rather than a question.

Bug report

Steps to reproduce

** English is not very good **

try change option config.js to be: markdown.extractHeaders:["h1", "h2", "h3"], on Post page, try to get this.$page.headers still return h2 and h3

and I changed the file: node_modules/@vuepress/core/lib/node/Page.js line117:

const headers = extractHeaders(
          this._strippedContent,
          ['h1','h2', 'h3'], // add 'h1' to here.
          markdown
        )

it worked.

so, I think markdown.extractHeaders option does not work.

What is expected?

on post page, get this.$page.headers includes h1 level

What is actually happening?

Other relevant information

"vuepress": "^1.2.0"

in Chinese:

制作主题时候，想通过设置makdown.extractHeaders, 来 this.$page.headers 获取到所有的heading 标签，感觉是硬解码写成固定的了，配置的选项也不生效。

Hi @Otto-J

Thanks for the report, markdown.extractHeaders option is currently not available in the 1.2.0 release.

This feature is implement by #1945 ,which is after the release of 1.2.0, please patiently wait for the next release. Thanks.

This issue is also related to #1931 , the document is updated faster than the release.

Thank you for this work as I tried to implement this in #1111 ... Is there any idea when the next release will happen which will include this work?
