Should this line also be in the if? If the size is unchanged then technically nothing changed and no new allocation took place.

Moved SizeAllocated(Width, Height); inside the if condition to ensure that it is only called when the width or height actually changes. This prevents unnecessary allocation when the size remains the same.

Should we wrap the whole block here as well with a check for if _frame != bounds? If nothing changes, then do nothing.

Added an early exit check (if (_frame == bounds) return;) at the beginning of the method. This ensures that the update logic runs only when bounds actually changes, preventing unnecessary processing.

Issue Details:
The SizeChanged event was being triggered continuously even when the width and height of the element remained unchanged.
Root Cause:
The existing implementation did not verify whether the width and height had actually changed before invoking the event.
Description of Change:
A condition was added to compare the existing width and height with the new values before triggering the SizeChanged event. This ensures that the event is only fired when there is an actual change in size, preventing unnecessary event invocations.
Tested the behavior in the following platforms
- [ ] Android
- [x] Windows
- [ ] iOS
- [x] Mac
