Favicon modification with Opéra browser

[mvy]

The favicon notification is not working well on Opéra browser.

Some times it does not show at all, sometimes it shows and never goes away.
I am having trouble to generate a good use case for both scenarios.

Anyway, I saw Opéra is using some kind on notification (folded corner) to indicate an activity in the tag. Maybe this function is messing with the script?

Unlikely. The folded corner notification is similar to what Chrome and Firefox does to notify the user of pages whose title has changed, and should not interfere with the userscript.

One oddity I did notice with the userscript is that on Firefox at least you have to view the chat page at least once before the script will work if you have them open at the start from pining them permanently. Not sure if this is due to the page or Firefox
