Search results sometimes got skipped

To reproduce:
1) Open the attached file in linguist.
2) Ctrl+F and search for: "tracepoint". Chosen options: "Comments | Source texts | Translations | Ignore accelerators". Click "Find Next"
3) Press F3, you should navigate to "Degugger::Internal::DebuggerPluginPrivate" context, with "0x%1 hit" source text.
4) Press F3 again, you should navigate to the next source text with "%1:%2 %3() hit".
5) Press F3 again, you should navigate to the next source text with "Add Message Tracepoint", but this is skipped (bug).

Notice, that while you navigate by mouse to the item mentioned in 4) and then if you press F3 you navigate properly to the next item.
