@DIR-825 - I watched your video but you didn’t actually show the issue you are claiming is a bug.
In order to prove that it is a bug, you must show the exact steps and problems so that other people can understand and reproduce it.
You should start with the default configuration on 19.07.1 and then show the exact steps you took that created the problem. We must be able to see the problem occur. You also need to show the problem happening in more than one web browser.
I do not believe that there is a bug. Instead, I think that the problem is related to the web browser and/or user error.
