1. Start Emacs with its own UI under X Window.

2. Type: M-<
   Here the cursor is at the beginning of the buffer, which contains
   some text.

3. In some other window, select some text (e.g. the letter "n").

4. Type: C-s
   This starts the interactive search. It says:
   I-search:

5. Click with the middle button near the bottom of the window.
   This pastes the text at the end of the buffer.

6. Type: C-_
   This removes the pasted text and moves the cursor back at the
   beginning of the buffer.

7. Type: C-s
   This starts the interactive search again. But this time, it says:
   I-search:  [No previous search string]

8. Type: e
   This searches for "e". All the occurrences of "e" are highlighted.

9. Type: <down>
   This is no longer the interactive search, but the occurrences of "e"
   are still highlighted.

Typing other letters brings back to the interactive search.

This is because clicking the middle button during isearch calls
isearch-mouse-2, which calls the usual mouse-yank-primary, which calls
isearch-done to finish isearch. Problem is, it let-binds
overriding-terminal-local-map around this call, which counteracts
isearch-done setting this variable to nil. The end result is having quit
isearch, but with the overriding map still in place.

I have attached a simple patch below. Eli, if it's satisfactory, would
you commit it for me?

TIA

IMO, it would be better style to do something like

(let ((binding (let ((overriding-terminal-local-map nil))
                 (key-binding (this-command-keys-vector) t))))
  ...)

Check https://debbugs.gnu.org/cgi/bugreport.cgi?bug=23007#8, we need to
avoid binding `overriding-terminal-local-map' in "...".

Clearly I, like you, meant that this let is for only the second
`if' clause.  But these are only style differences.

If it were I, I'd also move the let-binding that is used only
in the first `if' clause into the `if' test.  (And I'd ensure
that there is in fact a mark.)

(if (let ((win (posn-window (event-start click))))
      (and (window-minibuffer-p win)
           (not (minibuffer-window-active-p win))
           (mark)))
    (isearch-yank-x-selection)
  (let* ((overriding-terminal-local-map nil)
         (binding (key-binding (this-command-keys-vector) t)))
    (when (functionp binding) (call-interactively binding))))

Sorry for not being clear, but that's not what I meant:
`overriding-terminal-local-map' must be bound for the `key-binding'
call, and not for the `call-interactively' binding call.  See Alex's
explanation in message #8 and its attached patch.

My bad.  Sorry for the noise.

That was my first idea, but at the time I thought it was better style to
use the setq version instead. :)

Your version makes the binding more obvious, though, so I updated the
patch to use it. I've attached it below.

PS: I don't immediately see a reason to check for the (mark) in the
condition. I tested by deactivating the mark explicitly, and setting
mark-even-if-inactive to nil in the window, but it still worked
correctly.

You probably don't need it.  Sorry if I confused things, again.

[I use it because my code needs to work also in older Emacs versions.
So it first calls `gui-set-selection' to set the primary selection
on the region (when there is a mark).  And it `deactivates-mark'
before then calling `isearch-yank-x-selection'.]
