Anything else?

The STR were shown using the Count function, but correct searching behavior can be shown with Find Next instead by substituting this new step 5 for the step 5 in STR:

5. Press Find Next repeatedly; observe that Notepad++ will find the data at lines 7 through 8, then 1 through 2, then 7 through 8, etc. (good)

Reproduce the issue in Notepad++ using the Find window, selecting lines 1–2 and comparing Count with Find All in Current Document; Find Next provides a second comparison. Trace the Find window entry points for these commands and verify that Find All reports the same two occurrences as Count and Find Next.
