Emotes dialog box and similar dialog boxes / pop-ups on Facebook and other forums are showing on top of the page instead of showing at the comment box they belong to after latest update
So I'm using Firefox Browser Developer edition.
Ever since it updated to version 80.0b1 (64-bit), the dialog kind of pop-ups or tooltips or however they're called, are not showing properly, on sites like Facebook and other forums I use.
As you can see in the image, if you're typing on the text field, when you click the Emote / Emoji button, the pop-up window should be shown right below the text field, however ever since the update, they appear at the top of the page, making it impossible to use if the post I'm commenting on is deeper in the page.
It's really annoying, and that's just an example, but there are many other dialog kind of windows that are behaving similarly.
Deactivating add-ons didn't help.
This wasn't a problem before the update. Is this gonna get fixed? What is affecting its proper behavior? I'd appreciate any help.
