Like jasomill mentions, the browser playback issues statement has not been true on desktops for a long time. The most recent (or only) example I know of is iPhones, which finally added passable support for non-44.1kHz audio somewhere between iOS 15.7 (late 2022) and last august. Until then they'd sound like a broken vinyl deck when playing 48 kHz audio, oscillating in playback rate and crackling like crazy -- especially when passing through an AudioContext.
