When typing in messages on vk.com, the text jumps to the beginning of the message, what is it?

Question

In contact with

I type text in VK, after the first word, it throws it to the beginning of the message, and it is already written in front of the word that I wrote. You have to demolish the browser and reinstall it. On other sites, everything is printed normally, there are no problems, only with VK, some lags. Please help me, it's just that my brain is already exhausting, but I can't figure out what the problem is and how to fix it.
