I have enabled the Show website icons in tabs feature made available in Safari 12.
Gmail has a feature to show count of unread emails in the browser tab favicon. The count shown in the Gmail tab in Safari 12 is incorrect.
For these tabs, on the first I have a total of 4 e-mails in the inbox, while in the second I have 7. None of them are unread. These counts never change. Does anyone have a fix for this?
I'm running Safari 12.0 under macOS High Sierra 10.13.6.
