I want to change the position of an element dynamically via anchors, either to the right edge of the parent element or to the left. For this, I use anchors.left and anchors.right. When I want to display an element on the left, I assign parent.left to anchors.left and undefined to anchors.right. In the case when I need to display an element on the right, I assign parent.right to anchors.right and undefined to the anchors.left property. But this only works once, see the attached video. I also attach an archive with the source code for playback.
Here is a specific section of code for assigning the desired values:

anchors.left: isLeft ? parent.left : undefined
anchors.right: isLeft ? undefined : parent.right
