623 - Viewer minor Escape key issue

[Dreamer]

Just search for anything in viewer, text mode...

- open viewer
- press ctrl+f
- type any word which exist in the text
- press f3 to search next, as many times as needed
- dialog with text "Search match not found. Restart search from the beginning of the file?"
- now press Escape to close dialog
= nothing happens - dialog should be closed IMO

I'm not sure if it's a 100% bug, but for all other similar dialogs Escape key works as no/cancel and it's closed.
