bug#32990: 26.1.50; isearch-forward + t-m-m/mark-active doc

Thanks, I tried, and have one suggestion: due to the long menu it
doesn't fit into the frame's height, so to click an item at the end of
the menu requires scrolling that takes time to scroll.  I suggest to
create more submenus, for example, a Yank submenu for all yank commands.

> The Isearch menu now works when clicking the mode-line indicator and

I tried clicking Isearch items in the mode-line indicator such as
"Repeat search forward", but it cancels Isearch (and leaves Isearch
highlighting).

> tmm-menubar (M-`)/TTY menus (F10 from TTYs) should now work as

From tmm I tried "C==>Cancel last input item DEL", but it does nothing.
Do you see the same?

This duplicates the constant string " Isearch" in two places.
Why this change was necessary?

What problems caused adding force-mode-line-update?
