It was a difficult issue to fix, but now it's working in git master (9955d9e).

>From the commit message ----------

ContentProperty with collection caused unexpected read in XamlXmlReader.

The fix is actually complicated. When a ContentProperty list is settable,
NET allows omitting start element for it i.e. it *may* or *may not* appear,
which for each is interpreted as:
        - it is StartObject if the start element can be of the member.
        - otherwise it is GetObject.

It could still happen that if such a list could contain an instance of the
same list type, which results in "indeterminant" state. I don't think MS XAML
syntax and/or parser is carefully designed to treat such situation gracefully,
so I leave current implementation as is.
