Writer fails to find italics

In an ODT document I need to find all the words in italics. So I use Regular expressions, with .+ in the Find field, and choose Format ... > Typeface: Italic. I seem to remember that this always worked, but this time it doesn’t. Can anyone figure out why?

The attached ODT document contains 3 words only, with word no. 2 set in italics. When I apply the search above to this document, I am told “Search key not found”.
