[Talk-ca] openstreetmap.org tile rendering unreliable

[john whelan]

Then you're probably suffering from programmers writing the web site
optimised for something like Google Chrome.  About 90% of the market is now
Chrome or Edge which is Chrome under a different name.  Even Firefox is
down to single digits in market share so web sites are often only tested
and optimised for the most common browsers.

Each browser has it's quirks and Apple tend to not follow standards anyway.
