What steps will reproduce the problem?
(1) Open a large PDF document
(2) Press Ctrl+F
(3) Type a term that appears closely below the current page

What is the expected result?

As soon as the first occurrence of the search term is found, the viewport should jump to that occurrence. It should be possible to cycle through all the already found occurrences while the rest of the document is still being scanned.

What happens instead?

I see the total occurrence counter ("0 of <total>") counting up as more occurrences are found, but my viewport stays where it is. Pressing Enter of clicking the up/down buttons in the search box while in this state does nothing. Only after the whole document has been scanned does the viewport jump to the first occurrence (with the search box text changing to "1 of <total>").

This is a recent regression and used to work as described in "expected result" before (where you could cycle through occurrences while it's still searching... it would also wrap around when you cycled through the last *found* occurrence even though there may have still been others in later parts of the document, which was odd but possible to get used to). I work with many PDF manuals that are several thousand pages long every day, and searching through the whole thing can take close to a minute. Always having to wait for that although you know the rough area you want to find something in is a big productivity hit.
