Strange property changes when doing a ParentChange

When running the attached example in qmlviewer and clicking on the screen, the output is as follows:

===== state: inHolder =====
text: Dummy is in the holder
text: Dummy fills the screen
before ParentAnimation
after ParentAnimation
text: Dummy is in the holder

The expected output is:

===== state: inHolder =====
before ParentAnimation
after ParentAnimation
text: Dummy is in the holder

The spurious changes to the target value and back to the original value, only to finally change to the target value as the end, are not expected. Also, they do not occur when commenting out the ParentChange (but the ParentAnimation is not necessary to trigger this issue).

In my case I'm trying to set the source of an asynchronous Image element and these strange property changes are causing unnecessary reloading (which I actually wanted to avoid during the animation).
