This is expected behavior, sorry for confusing the issue when we were discussing it on Slack. The preferred behavior for file types doesn't normally apply to types that are supported in the browser, unless "content-disposition" is "attachment", which forces saving the file (and optionally prompting about how to view the file). The test plan for changing the preferred action shouldn't have included these links, that was my oversight when I added them to the test page.
