### Type of issue

Other (describe below)

### Description

In translated content on `learn.microsoft.com`, fragment hyperlinks don't lead to their corresponding heading.

For example, visit this page in German:
https://learn.microsoft.com/de-de/dotnet/api/system.text.regularexpressions.regex.replace

… and visit any fragment hyperlink in there.

Here's a non-functional example:
