In ebook-size builds, tcolorbox occasionally complains:
Package tcolorbox Warning: Using nobreak failed. Try to enlarge
`lines before break' or set page breaks manually on input line
xxxx.
This warning is accompanied by an unfortunate page/column break just
below a section heading in Appendix E.
Make such ugly breaks less likely by enclosing the \section command
with a pair of pagebreak/nopagebreak hints.

You need to be very lucky to observe this issue. At the moment,
you can observe it in perfbook-ebsf.pdf built on Ubuntu 22.04.
Section E.18's heading goes to the bottom of page 1277.
This change makes it go to the top of page 1278.
