Dead terminal buffer still lingers even after "exit"

[imranZERO]

I am using vim version 9.1576 and this bug didn't exist in the early versions of vim9.

Basically when I enter exit and kill a terminal session, the floating window disappears, and the next time I press <F12> which is mapped to <Plug>(Multiterm) a new terminal session is initialized; which is the expected behavior.

But now when I type exit and kill the session, the window closes but the next time I enter <Plug>(Multiterm) the previous dead terminal buffer is shown; and I cannot open a new window without bwipeout - ing everything.
