Code outlining keeps auto expanding

Hi Support,
I am experiencing 2 issues:
1) Code outlining is not initially displaying
2) Code outlining is auto expanding in an un-expected way when I edit the document

I have a small project that does the below and can send this if needed.

Thanks,
Tim

To reproduce:
1) Copy the XML Getting started control example to a new WPF project/Solution - removing the schemaResolver section.

*************** Outlining Not displayed ***********
1) Start project and outlining is not initially displayed
2) edit the document and outlining is displayed

*************** Outlining Auto expansion issue ***********
To reproduce V1:
1) Once outlining has started (see issue 1 above) collapse the sections for hair and behavior
2) edit the text in an attribute of the mammal element (eg: add a space at the end of the word "terrestrial"
3) the collapsed sections will auto expand

To reproduce V2:
1) Once outlining has started (see issue 1 above) collapse the section for hair
2) add a space anywhere in the elements behavior and communal
3) the collapsed section will auto expand
