Expander with a nested expander

[offan]

When a nested expander closes, the upper expander close.
Example
` <Expander
ExpandDirection="Down"

                        Header="Hidden Stuff">

                        <StackPanel Orientation="Vertical">

                            <TextBlock Text="...42" />

                            <Expander

                                 ExpandDirection="Down"

                                Header="Hidden Stuff1">

                                <StackPanel Orientation="Vertical">

                                    <TextBlock  Text="...43" />

                                </StackPanel>

                            </Expander>

                        </StackPanel>

                    </Expander>`

@offan Thanks for reporting this nasty behavior. This will be fixed in next release (final release).

The problem here is that the first parent Expander also get the Expanded and Collapsed events. So we must look for the OriginalSource which must be also the sender.
