DOM elements hidden
I am not sure if this is Mac specific but over the past 6 months or so I have noticed that quite regularly when I use the dev tools in Vivaldi, DOM elements start to disappear when I am changing their attributes/style etc. Everytime it happens I have to go to Chrome or Firefox to do what I was doing.
Is there a way to stop it from happening?
Basically whenever I modify the properties in any way, a small black dot appears next to the element in the elements panel and disappears from view.
Can not reproduce your issue on Windows.
