Ctrl+F not working

Hi, so we’ve enabled the free version of WP Content Copy Protection on our site (it’s a subscription-only digital publication covering business and tech) to test it out.

One odd thing that we’ve noticed is that the Ctrl+F shortcut to search in page is somehow disabled. It happens across Firefox, Chrome, Brave (Chromium) and Edge.

As far as I know, only shortcuts for copy, inspect page, etc. are supposed to be disabled.
