Trying to auto-number headings via external CSS style-sheets, I have partial success (i.e. the numbers are displayed in front of the headings). However when I select Control+A (to mark all), and then Control+C (to copy all to the clipboard), the pasted text lacks all the numbers in front of the headings.
I would expect that text displayed as marked actually will be copied into the clipboard.

Reproducible: Always

Steps to Reproduce:
1. Have content from a CSS "content:" statement displayed in your document
2. Select all (Cntrl+A), copy it (Cntrl+C)
3. Paste it into some text window (Cntrl+V)
Actual Results:  
Generated content is not present in the pasted text

Expected Results:  
Things that are displayed will also go into the clipboard when copying
