Bug 290851: www/chromium: emoji picker not working
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=290851



--- Description ---
I'm using https://github.com/GaZaTu/x11-emoji-picker to input emojis, but for
some reason Chromium seems to refuse letting it input stuff.

On Firefox it works just fine, and using Chromium on Gentoo also has it working
normally.

Since the tool relies on xdotool to input the emojis, I'm starting to think
there's something in the FreeBSD build that's affecting how it behaves in X11.
I can't point out what it is exactly, of course. I thought there would be a
flag for setting the default Ozone platform, but I couldn't find that, at least
not in chrome://flags.

So what could it be?
