"First paragraph" option (on frames/pictures) isn't saved if Wrap is Through

Steps to reproduce
1. create new text document
2. insert frame
3. set "Wrap" of frame to "Through" and select "Option"/"First paragraph"
4. save file (in OOo format)
5. open file
6. check properties of frame

Expected result
1. "Option"/"First pargraph" is selected

Actual result
1. "Option"/"First pargraph" is NOT selected


Note #1
- You can also insert a picture instead of a frame.
- You can also save the file in "StarWriter 5.0" or "Word 97/2000/XP" format,
"Option"/"First pargraph" will always be NOT selected.

Note #2
1. open saved OOo file in zip program
2. open content.xml
3. you'll see something like:

   <style:style style:name="fr1" style:family="graphics"
style:parent-style-name="Frame">
   <style:properties style:wrap="run-through" style:vertical-pos="top"
style:vertical-rel="paragraph-content" style:horizontal-pos="center"
style:horizontal-rel="paragraph"/>
  </style:style>

4. insert attribute/value style:number-wrapped-paragraphs="1" to the end of 
style:properties, so you'll get:


   <style:style style:name="fr1" style:family="graphics"
style:parent-style-name="Frame">
   <style:properties style:wrap="run-through" style:vertical-pos="top"
style:vertical-rel="paragraph-content" style:horizontal-pos="center"
style:horizontal-rel="paragraph" style:number-wrapped-paragraphs="1"/>
  </style:style>

5. make sure you're modified content.xml is in OOo file
6. open OOo file
7. check properties of frame
8. you'll see "Option"/"First pargraph" selected
9. add a space somewehre to be able to save the file again
10. save the file
11. open the file again
12. you'll see "Option"/"First pargraph" again NOT selected

This shows that OOo is ABLE to LOAD the property but NOT ABLE to SAVE the propery.
