Description:
When changing the style of a footnote separator to be right-aligned or centered, this style is only retained until the document is closed. Once it's opened again, the footnote separator is left-aligned.



Steps to Reproduce:
1. Create new Writer document
2. Insert footnote
3. Right click -> Page -> Footnote
4. Set "Position" to "Right" or "Centered"
5. Save document, close and open again


Actual Results:  
Footnote separator is left-aligned

Expected Results:
Footnote separator is right-aligned or centered


Reproducible: Always


User Profile Reset: No



Additional Info:
All other footnote-separator styles are preserved.

This is the relevant attribute  http://docs.oasis-open.org/office/v1.2/os/OpenDocument-v1.2-os-part1.html#attribute-style_adjustment

It is present in the saved filed set to "left". 

Manually updating the test.odt/styles.xml file and setting the value of 

/office:document-styles/style:page-layout/style:page-layout-properties/style:footnote-sep@style:adjustment

to "right" or "center" has no effect. After loading and saving such a manually edited document, the value of the attribute changes back to "left".
