Problematic focus when using company

[shrubbroom]

I am using emacs, whose version is mac-port 27.2. When company-mode is turned on and the tooltip pops up right after the first char is inserted, sort-tab will focus on wrong buffer.

The sort-tab should focus on the tmp.el, however, it focuses on the tmp.lua as I typed the firs char. The minimal configuration to reproduce the behavior is shown as follow.

(package-initialize)
(add-to-list 'load-path
             (concat user-emacs-directory "site-packages/sort-tab"))
(require 'sort-tab)
(sort-tab-mode +1)
(require 'company)
(setq company-idle-delay 0
      company-minimum-prefix-length 1)
(global-company-mode)

This behavior is not harming the functionality since sort-tab will focus correct buffer as more char is inserted. However, it may be annoying as the focused buffer changes rapidly. Modifying the following line may help.
From

LINE 280:sort-tab.el:   (let ((current-buffer (current-buffer)))

to

LINE 280:sort-tab.el:   (let ((current-buffer (window-buffer)))

I have no idea if this would break other functionalities.

I can't reproduce your problem, can you test with "emacs -Q" ?

Thanks

I can reproduce the problem with emacs -Q. After the emacs is started, I eval

(package-initialize)
(require 'sort-tab)
(sort-tab-mode +1)
(require 'company)
(setq company-idle-delay 0
      company-minimum-prefix-length 1)
(global-company-mode)

and create two new files. One tmp.c is just empty, the other one is tmp.el. When one char is inserted and company is active, the wrong buffer would be focused.

The sort-tab should focus on tmp.el rather than tmp.c here.

The version of my company is company-20220110.2248, the sort-tab version is HEAD. I have tried to reinstall company, but it doesn't help.
