Hello, Emacs.

In the emacs-27 branch, in X Windows, from a terminal:

(i) emacs -Q -nw.
(ii) M-x menu-bar-mode (to turn it off).
(iii) Visit a file.
(iv) C-s <some characters>.
(v) f10 to open the menu.

(vi) C-x o once or twice to move to the menu window.
(vii) C-g.  (This leaves the menu window in place).
(viii) C-x o to move to the minibuffer.
(ix) C-g.  (This deletes the menu window).

There is now one window open, that displaying the file buffer.
According to the mode line, Isearch is still active, and indeed further
characters can be typed onto the search string.

However, point can be freely moved by, e.g., C-f or C-b., without
terminating the Isearch.  This is a bug.

This is because 'isearch-menu-bar-commands' contains 'menu-bar-open'
added in bug#32990 to allow invocation of isearch commands from menu.

bug#32990 was a very long thread, so I didn't read that -- but does this
mean that the reported behaviour isn't a bug?

It's still a bug.  The problem is that when the menu-bar is disabled,
menu-bar-open calls tmm-menubar directly, but in isearch-mode
isearch-tmm-menubar should be used instead.  isearch-mode-map remaps
tmm-menubar to isearch-tmm-menubar, but this doesn't help
in case of menu-bar-open calling tmm-menubar directly.

I see no way to fix this other than handling isearch-mode in tmm-menubar:

Ah, I see.

It does seem a bit hackish, but I guess there's no other real
alternative...

Other alternatives would add more complexity via some redirections.
But since there are other places with special handling of isearch-mode,
this is not bad.  So now pushed to master.
