Useful or not, from you.
doom-emacs centaur-tabs' `gt`/`gT` asking for more key input.

What did you expect to happen?

When pressing gt or gT, the tab should be switched immediately.

What actually happened?

Instead of switching immediately, it stops waiting for another keystroke.

Describe your attempts to resolve the issue

I saw that if you press SPC or a letter, it switches tabs, but if you press an arrow key, the message "No replacement character typed" appears. This message seems to come from .local/straight/repos/evil/evil-common.el:609.

I removed my config and tested with the default doom config, and there gt is bound to workspace switching and works normally. Enabling tabs the bug appears again. I tried to remove the keybinding for workspace (in case it was conflicting) but that does not solve the issue.

Steps to reproduce

Install doom and enable the tabs module. Open two tabs and try to switch with gt.

System Information

That's a useful answer
Without any help

Simply replacing current-prefix-arg by index and restarting emacs resulted in the functionality not working anymore. gt took me to the last tab and then gT did nothing.
