Emoji in Title - Shows up in Browser Tab

[vintage-car-magazines]

I've come across a listing that has an emoji in the title. The weird part is that the emoji is also showing un in the browser tab icon. Images below are the beginning of the description and the tab. Any idea how something in the listing can impact the tab icon?

The tab title is almost always the title of the page on that tab.

Emoji's are nothing more than glorified unicode characters.👍

Doh....Mystery solved....I am a moron, lol

The tab ALWAYS shows the ebay logo AND the beginning of the title.

I had so many tabs opened, that I only saw the logo and emoji. Funny how you can see something so often and not actually SEE it.
