Unloading the only active tab in a window

[SeanMcMillan]

It used to be that if you used "Discard All other tabs" that it would still leave the active tab in each window loaded.

Now it seems to open a new tab that's (mostly) blank. And it's nice that that tab closes itself if you click on it, but now all of my windows are called "New Tab". And which adjacent tab gets focus seems unreliable. It's not always the one I was on. (Though this may be because of an interaction with my session manager.)

Can we get a setting to not discard the active tab in a background window, please?
