Using mouse in Completions buffer throws an error

[vadim-zyamalov]

Issue type

• Bug report

Environment

Emacs version: GNU Emacs 27.2 (build 1, x86_64-w64-mingw32) of 2021-03-26
Operating System: Windows 10 21H2 19044.1387
Evil version: 1.14.0
Evil installation type: straight.el (via use-package), I think it uses MELPA recipes
Graphical/Terminal: GUI
Tested in a make emacs session (see CONTRIBUTING.md): Yes

Reproduction steps

• Start Emacs
• Enter :, then start typing in any command (i.e. evil-).
• Press Tab
• When the *Completions* minibuffer appears try to mouseclick any suggestion.

Expected behavior

Clicked command is inserted into the command line (sorry, not quite familiar with Emacs terminology).

Actual behavior

I receive the following error:

mouse-minibuffer-check: Wrong type argument: window-valid-p, #<window 8>

*Messages* buffer shows the following messages before it:

Making completion list...
Quit
Error in post-command-hook (evil-ex-abort): (user-error "No recursive edit is in progress")

Further notes

The problem occurs specifically when I try to complete the command via mouseclick in the completion list for : (evil-ex-completion, if I understand correctly).
In other situations that allow using mouse (e.g. completions for eval-expression) mouseclicking works as expected.

I've added a small video from make emacs session:

Thanks for the bug report. Should be fixed in master. Feel free to reopen if you think otherwise.
