Wrapping missing in some circumstances causing an overflow

In some circumstances there is an overflow in the PDF output.

The YAML-header in index.Rmd:

The content of _bookdown.yml:

book_filename: "orgaanilise-keemia-raportid"
new_session: false
delete_merged_file: true
rmd_files: [
  "index.Rmd",
  "rmd/test.Rmd"
]

The content of _output.yml:

bookdown::pdf_book:
  keep_tex: yes
  latex_engine: xelatex

The content of rmd/test.Rmd:

# joppenpuhh

Vesi ja 2-hüdroksü-1,2,3-heksaantrihape ehk 2-hüdroksü-1,2,3-propaantrikarboksüülhape

After building the PDF version we can see that there is an overflow and wrapping does not take place.
