WhatsApp web bug with Firefox and KDE

I noticed since kubuntu 22.04 kde has this bug​ https://jrocha.dev/whatsapp-web-dele…to-no-firefox/

in short, whatsapp web deletes the first character when it is accented, for example, “é”, I noticed that it is from Kde because I tested it on Kubuntu, on Kde Neon and Debian with Kde and they all have the same bug, does anyone know how to solve it ?​

Have you tried this with another Browser or DE/WM? Possibly this is an issue with Firefox itself and not with Plasma?

yes, only firefox has this problem

I can reproduce your issue. But this is not a KDE bug.
The workaround mentioned in the post works for me.
