To be fair the browser default for stuff like this is often kind of bad. Like browsers would rather give you a scroll bar than do a word break (and I can pretty much guarantee that's what's happened here as I can scroll right and see the full number).
The Register kind-of models itself after a tabloid style so has deliberately jokey headlines. It's been around a long time (I read it in the 90s) and seems to have quality underneath the humor.
Possibly the only remaining place where you can read the word "boffins" regularly.
Yepyep, did the same on mine, I just zoomed the page out.
Honestly, really hope they did this on purpose, although I've seen plenty of cases where someone forgot to scale the text to Mobile and it went careening off-screen.
