Yes, it stays attached in the dynamic component options window.
I don’t know how I can find out what they really are… webdialogs or something else…
There is a small difference between them; rightclicking on the left doesn’t show anything (could be just disabled), on the right it does. A difference in frame buttons could also be just due to css-style.
I just installed M1 and on HtmlDialogs I now see the ‘inspect element’
On the dynamic component window (and all my other plugins still using webDialogs) there’s no inspect option
