Subject: [PATCH] Bump minimum Chrome version to 66 (#11995)

This PR updates our minimum supported Chrome version from 63 to 66, so that we may use the `AbortController` browser API without polyfilling it.

Our minimum Firefox version supports the `AbortController`, but our current minimum Chrome version (63, released in December 2017) does not. Chrome shipped the `AbortController` in version 66, in April 2018. We have determined that an extremely small number of users are on Chrome 63 < 66, and that this change is therefore acceptable.
