I have still an issue with messenger application (Facebook). This was the reason why I shifted to mozilla. And in Opera GX the problem still exist. While typing long message, the left bar is shifting above and above and there is a problem to get to the people from the top, mostly to people which are you typing now. This is so confusing...

On the picture you can see the issue with the bar which is moved upwards. Only the refresh button could restore it to the default value which is annoying
