Recently we started noticing in Safari v18.2 browser an unexpected useragent set for https://www.espn.com pages like -
"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/110.0.0.0 Safari/537.36" (recognized as Chrome by most UA detection logic) and breaks our video playback in some scenarios.
When digging into this we came across site specific quirks and the "Disable site-specific hacks" setting which fixed the playback functionality and set a more expected UA - "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/18.2 Safari/605.1.15".
Is the unexpected UA being set somewhere in Safari/Webkit? Can this be removed so site functionality works without needing to find the "Disable site-specific hacks" setting?
