href: broken links due to URL-encoding hash sign (# => %23)

I am trying to use an href linking to a web URL including an HTML anchor pointer. Hence I am using a hash sign (#) in the URL. For example to link the page https://github.com/latex3/hyperref#bug-reports.

Here is a minimal example:

documentclass{article}
usepackage{hyperref}
begin{document}

href{https://github.com/latex3/hyperref#bug-reports}{link with hash that doesn't work}

href{https://en.wikibooks.org/wiki/LaTeX/Hyperlinks#Commands}{link with hash where it works}

end{document}

The problem is that the hash sign gets replaced by the URL escape character %23 when the PDF is generated. If I click on the link in the PDF the browser will get the link in the following form:

https://github.com/latex3/hyperref%23bug-reports

But this leads to an 404-Error on GitHub.

If I replace the %23 with # in the address bar, the proper page can be loaded.

On other pages (for example wikibooks) links with URL-escaped # work (shown in the example above).

Is it possible to switch off url-escaping of the hash sign in links?

I am using pdfTeX 3.14159265-2.6-1.40.21 (TeX Live 2020) on MacOS Catalina.
