I have build 890 and while searching for something does produce results, F3 or clicking on a result does not take you there, you have to scroll to the line yourself

To get from one instance of a search term to the next you have to use the wee green arrows next to the search field.

I've had this issue off and on. Close the Editor, reopen and it will scroll the page to the first existence of the search term. Same with the green arrows not working to scroll to next or previous.
