Weird search behavior when query contains trailing space

To Reproduce
Steps to reproduce the behavior:

1. Search for a text with a trailing space, e.g. "dog " (in an attempt to find only complete word matches)
2. The first search result appears
3. Press enter or the next button to go to the next result
4. Sumatra doesn't try to find the next match.

Expected behavior
The next match should be found.

File that reproduces the problem

Additional context
This doesn't happen when searching for text without a space.

Adding "dog " since the above description does not provide a 2nd sample for matching but this page as PDF can.

So testing current find first and about to hit "next" (pale blue) > then agree it will not find second when there is a trailing space for test have attached this page at that point
