Someone said can you accidentally click a new tab button ...

The new tab button is specifically designed to be CLICKED .. it's a click magnet ... with multiple results - e.g. right click = containers menu, left click = newtab, and now middle-click (on linux). So it's VERY likely to be magnitudes of order greater as an accidental wrong click-type vs say, some page content. So to answer your question ... YES :)

Do we wish to do anything about this. Note, keyword.enabled = true, so this will leak to search engines. And URLs will go to URLs.
