Like in #2431 (comment), it would be good to have a test here that would also run on Windows. Modifying the texonly test should be sufficient.

Note: you should be able to set the DOCUMENTER_FIXTESTS environment variable to automatically update the reference .tex files:

Documenter.jl/test/examples/tests.jl

Lines 55 to 67 in c3c8754

	function compare_files(a, b)
	if haskey(ENV, "DOCUMENTER_FIXTESTS")
	@info "Updating reference file: $(b)"
	cp(a, b, force=true)
	end
	a_str, b_str = read(a, String), read(b, String)
	a_str_normalized, b_str_normalized = onormalize_tex(a_str), onormalize_tex(b_str)
	a_str_normalized == b_str_normalized && return true
	@error "Generated files did not agree with reference, diff follows." a b
	printdiff(a_str_normalized, b_str_normalized)
	println('='^40, " end of diff ", '='^40)
	return false
	end
