Which browser?
I m not on Mac but I've asked @quochuy and he uses Mac OS Catalina with Chrome and never got this problem. Also, have you tried disabling your other extensions to make sure it s not caused by one of them?

I am using chrome as well, sometimes Brave. Both have the problem. When I commented about the issue the first time, I saw someone say that he had the same issue on Mac with Firefox. My OS is Mojave though, maybe that's the problem?

I have not tried disabling other extensions yet. good luck to you and @quochuy!
