I was just wondering: shouldn't it be considered a bug the fact that on "Undo closed tab" only one tab remains? I mean, I have 2 tabs: one with a page and one with about:blank. I close the one with the page, then I choose "Undo Close Tab". The tab with my page is restored, but the about:blank tab disappears, so in the end I only have 1 tab. I see this as a bug - in the end I should still have 2 tabs.

Why do I see this as bug? Well, if I have 2 about:blank tabs and 1 tab with a page loaded in it and then close & reopen the tab with the page, the blank tabs are still there.

This happens on 3.6.3. Let me know if you need more info.

Thanks,
Alex
