Searching for text within blocks doesn't work

I have the word “Passport” in a block, but when i go to search for it there are no results. It used to work, now it doesn’t. Any idea why?

Did you use Ctrl+K for global search or Ctrl+F for local search by current page?

I have tried both. The problem seems to be with the nix package using the wrong electron version, but it is now fixed.
