Help validate deferred WaveSurfer seeks on physical iOS

[aribradshaw]

Goal

Confirm the deferred early-seek behavior in WaveSurfer PR katspaugh/wavesurfer.js#4353 on a physical iPhone or iPad.

Test matrix

• Safari on at least one current iOS release
• If available, one older supported iOS release or an in-app WKWebView
• Call setTime() from the WaveSurfer ready event before the media element can play
• Confirm the waveform reports the requested time, playback begins there after canplay, and later seek-bar interactions still work

Evidence to attach

• Device model, iOS version, and Safari or WKWebView version
• Requested time and audible/observed playback start
• A short screen recording or console event trace
• An exported Audio Browser Lab report for the exact asset, if possible
