Don't create a new scene when double-clicking empty space in scene tabs

[Calinou]

• Follow-up to Remove middle click shortcut to open scene tab #65302 and Get rid of mouse wheel switch in scene tabs #70800.

This behavior was often accidentally triggered when using the scroll tab arrow buttons. Web browsers also lack equivalent behavior, which means that it's not an UX pattern that people often rely upon.

If you need to create a scene quickly from the scene tabs, a "+" button remains visible at the right of the last scene tab.

• This closes Tab bars scroll buttons, double-click creates new empty tab #72313.

That's not fully accurate, Firefox behaves like this (at least on Linux).

I don't mind removing the feature (I don't use it).

Indeed, this feature exists, or at least existed, in various browsers and tabbed applications. So I think that the feature is fine. But navigation arrows should consume clicks.

I guess it depends on whether you have window borders shown, as doing this on my setup (which is also Linux) makes the window maximize itself (or restore itself is already maximized).

I think this was fixed in the TabBar itself by #79852

I can still reproduce this on 4.2.beta2:

This occurs even if double-clicking far away from the last tab (as long as you click on the TabBar area).

Oh, I meant the linked issue #72313 was fixed, so it doesn't trigger when using the scroll buttons.
I don't know if we still want the double click to create new tabs feature to be removed or not, since that seemed like the main issue with it.
