I'm attachng gif to show you the problem:
Unfortunately, I tried to reproduce this issue on your examples, but without success.
Do you have any idea where is problem?
Reproduced on the latest code, ticket opened here: https://github.com/bryntum/support/issues/4026 Thank you for report!
Did you notice this problem before you upgraded to 4.3.6? Which version did you use before that?
