table of content slugification differs from anchors slugification

🐛 Bug Report

If a header is called, for example, Tips & Tricks, the table of content section would slugify that as Tips-amp-tricks whereas the actual hash from the header is tips-tricks

This is more problematic than a mismatching anchor. Docusaurus uses scrollSpy, which fails to find the anchor like so: This exception then blocks lots of other functionalities on the page (e.g. code tab switching)

Have you read the [Contributing Guidelines on issues]

Yeah

To Reproduce

(Write your steps here:)

1. Write any markdown doc, add a header # Tips & Tricks
2. Check console

The problem comes from these lines: https://github.com/facebook/docusaurus/blob/6670c53d1838750de66ea2e6876da90d906428cb/packages/docusaurus-1.x/lib/core/toc.js#L40 https://github.com/facebook/docusaurus/blob/6670c53d1838750de66ea2e6876da90d906428cb/packages/docusaurus-1.x/lib/core/anchors.js#L25

If you console.log(rendered) in the first snippet, the sanitization turns Tips & Tricks into Tips & Tricks. Whereas if you console.log(textToken.content) in the latter snippet, it’s still Tips & Tricks.
