Steps to reproduce the problem:
1. Open any PDF file using the PDF viewer.
2. Search for any text. A box containing the search text and the number of search results appears. Specifically, the number of search results appears as a "x of y" string where x is the current search result number and y is the total number of search results.
3. Go to the next search result using F3 or go to the previous search result using Shift+F3.

What is the expected behavior?
x should increment when going to the next search result using F3. x should decrement when going to the previous search result using Shift+F3.

What went wrong?
x remains constant when going to the next search result using F3 or going to the previous search result using Shift+F3.
