Open a document with several matches on different lines, select one of them (with all others visible) and resize the window in such a way that some matches stop being visible - the highlighting (#1) will still indicate that all matches are visible.
This is especially troublesome with Edit Word (#18): if you resize the window so the match with the caret moves off screen and press Ctrl+Tab, you'll see the document is scrolled and the tooltip (Editing %d occurrences) appears around that match (off-screen) and yet it won't be made part of the edit region.
