I realized that Chrome will not emit this as a warning if the code is executing in the `beforeunload` block.

https://chromium.googlesource.com/chromium/src/+/1d328b0e963f7af9e63a4ceeb6bab908b566c848/third_party/blink/renderer/core/xmlhttprequest/xml_http_request.cc#699

Thus, I think it's reasonable to extend this as well to the `DOMContentLoaded` block.
