Some `{Pxxx}` links are not working

[prabau]

Some {Pxxx} links don't seem to be working on the web site. Here are some examples.

https://topology.pi-base.org/spaces/S000086:
Last sentence: "This provides an example of a {P123} space that is not {P3}, but is {P86}."
The P3 link is not working, but the other ones are fine.

https://topology.pi-base.org/theorems/T000363:
The links for T3.5 or T1 don't work for me.

Many other examples (both with Firefox browser and with Microsoft edge browser).

Can someone confirm that you also see the same problem on your machine?

I'm not seeing this bug in Firefox or Chrome this morning on my laptop.

Hmm, strange. I cleared the browser cache and all the cookies on Microsoft Edge for example, and I still see the same problem with the two links above.

In particular, for https://topology.pi-base.org/theorems/T000363, the T1 link from the theorem title works, but not the one from the text itself. That particular one leads to https://topology.pi-base.org/theorems/undefined ("404 Theorem not found undefined"). And same for the link from T3.5 from the text.

Maybe a clue: the links that don't work come from {P2}, {P6}, etc with a single digit after P.

But not a showstopper. The site is still usable overall.

This is already solved by #215, pending merge. @StevenClontz @prabau
