Site Search with Tab

As a new user I am not sure if it is a bug, missing feature or I am just not capable to get the settings right.

Description of the issue: In the settings “Manage search engines and site search” Brave does offer me the option to use Tab to trigger site search as I used it with Chrome. However, always when I press Tab after typing in the shortcut it selects some element in the browser (leaving the address bar).

I don’t want the address bar to expand or something else. I just want to type in the shortcut (in the picture it is “beck”) and hit tab an then write my search.

Operating System and Brave Version(See the About Brave page in the main menu): Windows 11, Version 1.67.119 Chromium: 126.0.6478.114 (Official Build) (64-bit)

Thank you!
