Hi. When I dragging a link over the tabs bar, I can drop it between 2 tabs; this will open a new tab for this link, which is a great feature. However if I (accidentally) drop it right onto an existing tab, that tab will be replaced with the new link; if the tab had anything important (could be a long, JS-loaded waterfall page), it will be gone. I have multiple bad experiences due to this bug/feature. How to disable this?
