Well spotted!
The thing is I had the following rule in uB0's My Filters
! Block globally AdobeDTM SatelliteLib scripts
||adobedtm.com^$third-party,important
... since many months ago , so that's why I was able to load the referenced links in my previous post ...
The crux of the issue is UXP's incompatibility with the SatelliteLib Adobe are including in their tracking scripts , so yes, ALL UXP- based browsers/forks are affected... In fact, if you search for "adobedtm.com" in the official PM forums, you'll discover many related cases:

I think the issue for me was first manifested on Oracle's site (see here) and I now remembered I actually sought help here in these forums about it ; solution was provided then by @UCyborg, further analysis by yours truly can be read here ...
Nothing to do with the Windows XP OS per se (apart from the fact it won't run the latest versions of Chromium and siblings (including Firefox Browser), on which the Adobe tracking scripts are made/tested to work without issues...).
Generalising is easy sometimes, but not necessarily the truth ... 360EE browser, based on recent versions of Chromium and made XP/Vista-compatible, has no issues dealing with the adobedtm scripts and, thus, with the sites that make use of it... But, being a Chinese product, it isn't easily endorsed by the XP community... Anyhow, 360EE is OT here and has dedicated forum threads (with some enhanced activity lately... )
Best wishes
