unknown cross-reference number with gitbook #787
Description
The gitbook version displays ?? instead of the correct number when cross-referencing headings that are followed by a higher level heading instead of a paragraph. This occurs in the example below with Part I (always) and Chapter 2 (with split_by: "section+number" not with split_by: "chapter+number")
The pdf output works as expected.
MWE

title: "My book"
site: bookdown::bookdown_site
output:
bookdown::pdf_book: default
bookdown::gitbook:
split_by: "section+number"
