Vimium conflicts with the "Ctrl + [" Keyboard Shortcut

Describe the bug
Include a clear bug description.
When using Google Keep, pressing Ctrl + ] indents an item of a list. Ctrl + [ dedents an item of a list. Vimium prevents the dedent Keyboard Shortcut to execute. When pressing Ctrl + [, focus is also removed (the caret disappears) from the list. I haven't been able to identify where the focus goes. I've tested and isolated every other Add-On, and I've identified Vimium as the culprit. Without extensively testing elsewhere, there also seems to be some funny business going with Google Docs.

To Reproduce
Steps to reproduce the behavior:

1. Go to URL Google Keep
2. Click on Check Box Icon to Create New List

Include a screenshot if applicable.

Browser and Vimium version
If you're using Chrome, include the Chrome and OS version found at chrome://version. Also include the Vimium version found at chrome://extensions.

If you're using Firefox, report the Firefox and OS version found at about:support. Also include the Vimium version found at about:addons.
Firefox 111.0.1 (64-bit)
Vimium 1.67.6

Initial List:

Indent of an Item:

Attempt of Dedenting an Item:

Start by reproducing the shortcut conflict in Firefox 111.0.1 with Vimium 1.67.6 at Google Keep, using the list and dedent steps described in the issue. Done means Ctrl + [ dedents the selected list item without removing focus, while preserving expected Vimium behavior elsewhere, including the reported Google Docs concern.
