A more direct solution, which I find slightly preferable, at least until I retrain to double-click when I want the tab to remain open:
In the settings, set preview_on_click to false .
This is not exactly what I want, since all he does is disable the behavior to open the preview tab with one click - thereby forcing the user to always double-click. But perhaps working this way for a week or so, I can retrain my deep-rooted assumptions and return to the default behavior.
