Done, thanks.

I've consolidated the list of commands into
'isearch-menu-bar-commands' (list of commands that can open a menu bar
during Isearch). I also updated 'isearch-mouse-leave-buffer' to allow
commands listed in new var 'isearch-mouse-commands' (list of mouse
commands allowed during Isearch).

'isearch-scroll' does not work on 'isearch-tmm-menubar' since
'isearch-tmm-menubar' runs arbitrary Isearch commands and can
therefore move point, which violates 'isearch-scroll's main
requirement.

Done, thanks. I'm attaching the latest change again.
----
* lisp/tmm.el (tmm-menubar-keymap): New function factored out from
'tmm-menubar'.
(tmm-menubar): Use 'tmm-menubar-keymap'.
(tmm-prompt): New optional argument 'no-execute'.
* lisp/isearch.el: Declare the new, non-autoloaded function
'tmm-menubar-keymap'.
(isearch-tmm-menubar): New function.
(isearch-menu-bar-commands): New variable.
(isearch-menu-bar-yank-map, isearch-menu-bar-map): New variables.
(isearch-mode-map): Define a menu-bar search menu and remap
'tmm-menubar' bindings to point to 'isearch-tmm-menubar'.
(isearch-tool-bar-old-map): New variable.
(isearch-tool-bar-image): New function.
(isearch-tool-bar-map): New variable.
(minor-mode-map-alist): Add an entry for Isearch so that
'isearch-menu-bar-map' shows during search.
(isearch-mode, isearch-done): Save and restore possible
buffer-local 'tool-bar-map' using 'isearch-tool-bar-old-map'.
(iseacrh-mouse-commands): New variable.
(isearch-mouse-leave-buffer): Allow commands in
isearch-mouse-commands.
(with-isearch-suspended): Only push changed states of Isearch
after running the body argument of this macro.
(isearch-pre-command-hook): Additionally allow bindings in
'isearch-tool-bar-map' to pass through, as well as commands
in isearch-menu-bar-commands.
(isearch-post-command-hook): Call 'force-mode-line-update' at its
end to make sure the menu- and tool-bars are up-to-date.
