Change the element's width at runtime doesn't update quickly in Mac and iOS platforms

[SethupathyD]

Description

I have implemented a custom control using ControlLayout. When changing the width of controls using pan gesture events, it leads the performance issue. It takes time to arrange the elements in the UI in Mac and iOS platforms. I had attached the video for your reference.

DemoVideo.mp4

Steps to Reproduce

1. Clone the SimpleSample from the repository.
2. launch the sample in MAC.
3. Try resizing the 0th cell with background color as LightBlue.

Expected Behavior - Cells should arrange without lag.
Actual Behavior - Cells are arranged with lag.
