Chrome itself always requests HTTP first, except for HSTS and their own pinned certificates list which is actually shipped within the source code. That's also a major difference to Ungoogled Chromium, where UC will request "https:// https://..." by default if you just enter the domain.

But usually employers that encourage such bad practices also install their snakeoil MITM certificates locally.
