And just a tip, if you don't have any Apple devices but need to test a bug/inconsistency being reported by Safari users, you can usually use GNOME Web (Epiphany) and the same behavior will usually manifest, since it is a true Webkit browser. It also includes the Web Inspector with the exact same interface as Safari. And it's not super outdated or anything like that, it tracks Webkit quite well nowadays.

It's a bit ironic that Webkit started as KHTML, a component of KDE, but eventually made its way to GNOME when a Gecko-based Epiphany became hard to maintain.
