Binding to an object fires erroneous reactive update

[intelcentre]

Describe the bug
When binding a complex value such as an object to a component <Component bind:value />, additional reactive updates are fired for the bound value even when no data is changed.

May be related to #4430 ?

To Reproduce
Simply bind a complex value to a component property.

Example:
https://svelte.dev/repl/5e14759de70d4d39b6f3833f91db4542?version=3.29.7

Expected behavior
Reactive updates should be consistent between simple and complex types

Severity
I find it irritating, but not a blocker.
This issue is most likely to cause redundant calculations without formally breaking anything.
This issue will likely snowball if components are nested, though I have not confirmed this.
The additional updates are likely to confuse people causing unnecessary work.

Additional context
Add any other context about the problem here.
