@dave.dillon - I hope you’re doing well!
I’ve spoken with the support team at Pressbooks to narrow in on the formatting issues we found in the book’s Glossary, where URL text would not wrap properly to adjust to the page widths. The main culprits have to do with the changed font-size and line-height of body text in the book, and the Pressbooks team will be looking into resolving this bug.
For the moment, however, they have recommended a short-term solution: reset the font, font-size, and line-height on this particular table to the original settings. This does resolve the text-wrap issue, however means that text in this Glossary table is slightly smaller than the rest of the body text (and also in a different font). See a screenshot of how this solution might look in the PDF:
Would you want to go ahead and implement these changes? I could make the necessary adjustments, and leave it to you to pull a new set of exports and formats when you have wrapped up your semester.
Let me know how you’d like to proceed, or if you have any questions. I will keep you posted if I hear anything more from the Pressbooks team.
