📝 Provide detailed reproduction steps (if any)

Please provide the steps to reproduce and if possible a minimal demo of the problem via fiddle.tiny.cloud or similar.

1. Open default fiddle (with autolink plugin)
2. Paste "https://github.com/&sect"
3. Observe that the URL is converted to "https://github.com/§"

✔️ Expected result

URL pastes as "https://github.com/&sect" and automatically converts to a link

❌ Actual result

URL converts to "https://github.com/§"

❓ Possible solution

One workaround is to paste as "https://github.com/&sect", either by copying that or using paste_preprocess.

Are there certain symbols that aren't valid in URLs? Or any way that we can convert the ampersand (&) in unclosed encoded character strings into "&", so that the URL is still pasted as valid?

The main occurrence is when a URL contains "/&section=", which is quite common.
