Description

We've known this for a few years, but I realised we never reported it to Apple, so let's do this.

Previous reports and data:

2015: T116713: Investigate nonCompliant errors for Navigation Timing schema (5% is ignored)
2018: T190977: Investigate NavigationTiming.nonCompliant error increase

From T190977:

Safari and WebView on iOS 8.0 (iOS 8.0 introduced broken navtiming, removed in iOS 8.1)

Safari on iOS 9.0 (iOS 9.0 introduced a differently broken navtiming, fixed in iOS 9.1 for Safari)

WebView on iOS 9.0 and later (iOS 9.1 did not fix navtiming for WebView, and remains broken)

Upstream: https://bugs.webkit.org/show_bug.cgi?id=186919

Data:

Public data - Grafana: EventLogging-schema / NavigationTiming
Detailed data, journalctl as per https://wikitech.wikimedia.org/wiki/Performance/Runbook/Webperf-processor_services#navtiming.
