Missing values in localStorage

Hey there!

First, I randomly stumbled upon this module and I'm super happy I did. It solves one of the main issues I have with the UI of Layout Builder. Thanks a lot for your effort!

I have one problem though: It works well when clicking on one of the prerendered list items of a block. But when I search for a block and the list gets built in the browser, the links become invalid (they contain 'null' instead of region, delta and node):

/layout_builder/add/block/overrides/null/null/null/block_content%3A8d0a950b-d6e9-4518-8f7c-cf87e8cfb5ff

A quick look at layout_builder_simplify.search.js shows these values are read from localStorage:

var r = localStorage.getItem('Drupal.layout_builder.region');
var d = localStorage.getItem('Drupal.layout_builder.delta');
var n = localStorage.getItem('Drupal.layout_builder.node');

All these keys don't exist in localStorage for me. I looked through the source of layout_builder's JS file and was not able to find a reference to where these items are set.

It's possible one of the other contrib modules installed in my project overrides this or I'm missing a module that sets these items.

Any idea what could be the issue here?
