Font ligatures in wiki pages

Hi,

I'm not sure whether this is the right list to post to, I apologize if it
isn't.

The RFC pages on the wiki site show unwanted ligatures. For example, the
word "ffi" on this page:

https://wiki.php.net/rfc/namespaces_in_bundled_extensions

is rendered this way on my machine (Chrome, Linux):

I think it would be wise to use this CSS rule on the whole website:

font-variant-ligatures: none;

Kind regards,
