I have one particular tab group that stores a lot of tabs that I keep collapsed when not using them, because otherwise they clog up my tab bar. But with the new collapsed tab group preview, when I scroll along my tabs my screen will randomly flash with a full page of tabs, as there is no delay on the preview. I don't think this feature was designed with dozens of tabs with long titles in mind. The ability to have a delay on the hover effect, or preferably to disable it all together, would be much much much appreciated.
