textbook boxes for exercises break in the middle of the page

Does this issue also appear

• after numerous compiles of the main document
• when memoize, tikzexternalize, externalize from forest and all other externalisation measures are disabled completely?

[stefan11]

I took out memoization by loading nomemoize. Other externalization is not used any longer. Memoization is supposed to do all externalization. Yes, after two further compiles it is still at the same place.

Currently it looks like this:

These were two consecutive page.

The issue is most certainly related to mdframed's settings skip{above/below}.

@stefan11 Can you please check whether this is fixed throughout the book after the patch in https://github.com/langsci/25/commit/80ba6f3c549b0a6770aa47f435c268847673b5b8 ?

I've checked it in 2-psg.tex but there may be other instances where it does not work so well.

[stefan11]

Yes, seems to be perfect now:

In case boxes ever get too close / overlap each other, this may be due to stretchable spaces between them, which are minimised (too much) such that both boxes can fit on one page.

While there is currently no principled solution against this, a possible workaround could be to enlarge the type area of that particular page, by inserting \largerpage or \largerpage[2] between the two boxes. I'd be grateful for some feedback if that strategy worked (if you come across a page in your book where you need that fix).
