If a property override added an IResolvable as the value,
it would not be resolved,
but instead treated as a CloudFormation object when rendering the resource's properties,
which would lead to some weird behavior
(the properties of the IResolvable would be merged into the template).
This was noticed by a customer using CFN-Include.

As a solution, resolve the overrides before merging them with the properties of the resource.
