Problem
On this query: https://tools.wmflabs.org/interaction-timeline/?wiki=metawiki&user=TBolliger%20(WMF)&user=SPoore%20(WMF) and this query: https://tools.wmflabs.org/interaction-timeline/?wiki=enwiki&user=Trevor%20Bolliger&user=RSound Safari throws this error:
The error reads: Can't find variable: IntersectionObserver
I'm on Safari Version 11.0.3 (13604.5.6) — OSX 10.13.3. Works fine in Firefox and Chrome.
The zero state loads fine, but when the three query parameters (user1, user2, wiki) are provided it throws this tantrum.
Expected behavior
- Timeline should fully function in Safari browser
