Add option to disable closing of browser when closing last tab

I can’t understand why all browser makers except Opera and Vivaldi force this crap on us? And even if you make it enabled by default, at least give us a bloody option to disable it. Like it can at least be done in Firefox through about:config. In Edge, Chrome, Brave, you just can’t do ANYTHING about it except use useless crappy extensions that are all like terrible hacks to bypass this nonsense.

Put the setting under Flags menu, I don’t care. Just put it there. Would be even better if it’s in actual settings, but I’d be fine with Flags too.
