Strange icon for Zabbix Documentation on iOS?

[marianogedisman]

I have Zabbix Documentation page (https://www.zabbix.com/documentation/5.0/en/manual) saved as Bookmark on my iCloud account (shared amongst devices), when I opened my favourites on iPhone, I see this:







It looks normal on my laptop though:



Anyone know what kind of mysterious icon is this?

Thanks!

A few months later (Today) I was looking for a Wiki software for my team, and lo and behold:



Maybe the Zabbix team was using DokuWiki at some point? Maybe at some point there was a Wiki instead of the documentation page, and it kept the favicon in some obscure cache? Maybe the documentation page is based on DokuWiki???? More questions than answers!
