Schema Inaccuracy

If I summarize https://api.github.com/repos/OWNER/REPO/compare/TAG1...TAG2?page=1&per_page=100 and compare it to its html equivalent, the html page gives 812 file changed with 4889 changes.

As expected, when I implement paging, I get 9 pages, but the first page is incorrect:

Comparison --
Page: total files: 300, total commits: 100
Page: total files: 0, total commits: 100
Page: total files: 0, total commits: 100
Page: total files: 0, total commits: 100
Page: total files: 0, total commits: 100
Page: total files: 0, total commits: 100
Page: total files: 0, total commits: 100
Page: total files: 0, total commits: 100
Page: total files: 0, total commits: 6

Expected

According to the docs for comparison, "The list of changed files is only shown on the first page of results, but it includes all changed files for the entire comparison"

To Reproduce

I just used the paging API per the docs. I consume the link header on each response and, starting with 1, increment the page query parameter as long as next returns true in the header value
