The above requires 1.73.95 or higher for 1.73.x verification 👍 As per brave/brave-core#26781 (review), loading alwayshttp.com takes a while which is expected. Also double checked with @stoletheminerals & @kylehickinson via Slack. Can use the STR/Cases from brave/brave-core#26781 (comment) as a template for 1.73.x verification.
