Code snippets header selection is not visible on Firefox

When selection the text of the header of the snippet, it works well under Chrome:

But under Firefox, the selection is not visible.

This is a bit problematic since the user often wants to copy-paste the filename in the header.

Example of a page where the bug can be reproduced: https://docs.djangoproject.com/en/3.0/intro/tutorial02/#id2

Just to clarify: The filename in the header is visible. But when you select it with the mouse, you can't see what's selected.
