Why emoji picker default on?

I'm running a nixos linux machine with Hyperland as my window manager and a few month back (likely after an update) I noticed that firefox started showing a emoji picker when I pressed ctrl+.. This was a bit annoying since the firefox extension for my password manager is activated by that key shortcut. I figured this was some update for firefox, but now that I dug into it to fix it it turns out that it is a gtk thing that apparently each app has to opt out of! I could disable it by flipping widget.gtk.native-emoji-dialog in about:config, but this seems like a really bad choice by gtk. Two gripes with this:

1. Them adding a global keyboard shortcut for all gtk apps that is ON by default (for a kind of niche usecase).
2. Overriding shortcuts on a desktop wide basis with no meaningful (afaict) way to disable it.

Anyone knows if this is intentional? Maybe it's already been reverted upstream and I just need to update... anyway end rant!
