Describe the bug
When the "Always on top" option is enabled, previews for emotes/links appear behind the app
To reproduce
Enable "Always on top" and hover mouse on top of an emote or link (nothing will seem to appear because it's behind the app)
Screenshots

Chatterino version
Chatterino 2.2.2 (commit 07fc0c3ad)
Operating system
macOS Big Sur 11.0
Someone else also confirmed that this is a bug. Highly doubt we will fix this though since it's mac only.
@gempir Could you please test this when you get the chance? 馃槃
Yeah confirmed on Chatterino 2.2.2 (commit d56187fda)

Happens for me too on Linux Mint 20 with Chatterino 2.2.2 (commit 98762fdfa) when opening usercards, but not on emote hover
@tintinmaster That's a completely different issue.
