Link Map window intercepts OS-level shortcuts

[andrewzhurov]

Description

When the extension's window is in focus it intercepts all keystrokes, making OS-level shortcuts unavailable.
I'm not sure if that's the issue with the extension or my OS poorly managing it's window.
If you think it's not extension-related, please feel free to close this issue.

Steps to reproduce (if applicable)

Install this distribution of Guix.
Install Chromium.
Add the Link Map extension.
Open it.
While it's in focus execute any OS-level shortcuts. E.g., Win+Shift+D or Win+Shift+C.

Expected behavior

Shortcut executed.

Actual behavior

Shortcut is not executed.
