(1) Select "Enlarge text size" from "View" menu, setting text size to larger than default. (2) Visit URL above. Paragraphs are formatted so that lines are longer than the current window width (I think this is a bug). (3) Select "Reduce text size" and then "Enlarge text size" [returning text to the size used in (2)]. (4) Paragraphs are now formatted so that lines are the same width as the window. This is inconsistent with the original formatting seen in (2). (I think that the formatting seen now is the correct formatting). Note that if (2) is infact the intended behaviour [having enlarged text size causes lines to be longer than window width], then (4) is a bug.
This is partly a duplicate of bug 35681 and partly a duplicate of another bug whose number I forget (and I'm not 100% sure this bug exists...).
The other bug is bug 42650.
For me (Linux 2000061908) the lines are longer than the current window size when I visit the link with normal text size.
resolving as INVALID based on david's comments that this so-called 'bug' is really just the combined result of two independent, more specific bugs
