What steps will reproduce the problem?
(1) Open a window with a single tab.

What is the expected result?
Either we go all-in on single-tab mode (hiding the "×" and tab separator, making the tab title look like a title bar; see  Issue 854007 ), or we remove it (it's just a single tab).

What happens instead?
The tab decoration is removed, so it doesn't look like a tab, but some arbitrary distance to the right of the tab title, there is an "× | +" which looks like some kind of introduction to elementary arithmetic.

At least get rid of the "×" which is redundant for the "×" in the top-right corner of the window.

Context: As discussed on  Issue 848380 , single-tab mode seems to be struggling to find an identity; it can't really occupy the full width (essentially becoming a single window without a tab) and there were complaints about the New Tab button being in the top-left corner. The recent change seems to have reverted most of the unique differences about a window that has only one tab. But this leaves it in a state where it just feels arbitrarily different to multi-tab mode with no clear advantage to doing so.
