Problem description: 

If one copies the markup of a formula and wants to paste it somewhere, it always appears at the end of the document

Steps to reproduce:
1. Create new Writer document
2. Type a single line, enter an empty line and type another line
3. Type sqrt{1} in the second (empty) line
4. Select 'sqrt{1}' and click on 'Insert->Object->Formula'
5. Double-click on the formula and copy the markup
6. Click somewhere in the text to close the markup window
7. Place cursor behind the formula and hit Ctrl V or select insert in the context menu


Current behavior: The text gets inserted at the end of the text

Expected behavior: It should be inserted where the cursor is
