I don't see the problem.
I have to guess that where you talk about another window you actually
mean another tab page, otherwise the tab pages line isn't displayed at
all.
I only see the "Tst#N" displayed when I switch between tab pages with
"gt".
I guess your example is missing something essential. Try starting with
"vim -u NONE".
