Juri, this is a direct consequence of your changes in commit 8230a47:

      * lisp/help.el (help--analyze-key): Prefer posn-set-point over 
mouse-set-point

      * lisp/help.el (help--analyze-key): Use posn-set-point instead of
      mouse-set-point that runs the hook mouse-leave-buffer-hook via
      mouse-minibuffer-check.  Using posn-set-point also unnecessitates
      extra conditions added in bug#51421.

The sad part is that the "unnecessary extra conditions" added in
bug#51421 fixed the very problem that your change now reintroduced.

Did you test that change with the original recipe which was solved in
bug#51421?  Did it work for you back then?

Any suggestions for how to fix this regression, except by reverting
the above commit?
