This morning upgraded to Version 7.6 (457299 App Store) Editor: 59.0.7031 (d523909) on my Mac with OS X 10.14.1 (Mojave)
I searched for a word, and found the note I wanted to add to, and each instance of the search term was highlighted (all as expected). I went to scroll to the bottom of the note and the UI elements highlighting the search term didn't move, at all (unexpected). I had expected the highlighting element to move with the term it was attached to.
I did not see this behavior before upgrading.
Screenshots of the note immediately after clicking on it from the search results, and after scrolling the window a little:
