No editor window popup and the property item can't be select after click "Set Expression" of "Follows current" property of qt quick PathView control.

Steps:
1. Open a qml file in designer mode.
2. Add a "PathView" control to the canvas.
3. Check "Follows current" property and try to use set expression of this property.

Expected Result:
expression editor pops up. and the property can be modified normally.

Actually result:
No expression editor window pop up, and "follows current" property can't be select and edit.

Other Information: I think "highlightFollowsCurrentItem : bool" is not a property of "PathView" control. So it needn't here.
If you change the "Follows current" in designer, there is nothing change in code.

This issue don't happen all the time, but often happens.
