Bug report

After null coalescing PHPStan loses type information on all other properties of the array. The new type of those properties becomes a union of all used types in the array (e.g. bool|int|string|null). This error only happens when the array contains 63 or more properties. See snippet for more information.

Code snippet that reproduces the problem

Expected output

PHPStan should remember the type of all properties in the array, regardless of usage of null coalescing or amount of properties.
