Can't upload emoji from my web browser

Can't upload emoji from my web browser(i use firefox)

I tried both English and Japanese UI.

File selection works without problems with BOT icon settings, server icon settings, etc.

It seems that the same problem has been occurring for two years, but is there any plan to fix it?

Japanese.
絵文字のアップロードがWEBブラウザから出来ません。
日本語UIと英語UIの両方を試しました。
WEBブラウザ版ではBOTのアイコン設定やサーバーアイコンの設定などは問題ありません。
