[Issue] MultiDataViewer: Find next only works at second try after Find Previous

[Jungle]

1. Find some text (which occurs multiple times) in a file
2. Find next several times
3. Now Find Previous.

Result: selection immediately jumps to the previous result

4. Now Find next

Result: nothing happens

5. Find next again

Result: now selection jumps to the next result
