Hello @timmse ,
I would expect that the popup stays open after clearing one style as there are usually a lot more options/styles in there that I am also editing and most usually I need to take another look at.
Say for example a Typography popup that has a lot of such sub-options. When I clear one of them, I want the pop-up to always stay open as there are other options in there that I need to take a look at before closing it.
I would only expect the popup to close when I clear the MAIN style, in my typography example, when I press the X button on the main typograhpy menu that openend the popup in the first place.
Here is a screenshot of a typography window. Say I need to clear the Alignment style, then I want to have a look at what other options are left here not auto-close this popup.
Hope I explained this well enough
