Did you check the latest version of Handsontable v14.4.0? We had a similar issue fixed. If so, please tell me, does the issue occur on all of the browsers and systems?
Hey!
I have been facing the exact same issue, I came looking here for a solution and I did what you (@aleksandra_budnik ) mentioned, upgrading to 14.4 (from 14.3)
However, the issue still remains unresolved. I have a video, but it cannot be uploaded here so please make do with the image attached.
In my case, the language used is Japanese.
