Invoked with an options object whose `maxByteLength` property cannot be
coerced to a primitive value
info: |
SharedArrayBuffer( length [ , options ] )
1. If NewTarget is undefined, throw a TypeError exception.
2. Let byteLength be ? ToIndex(length).
3. Let requestedMaxByteLength be ? GetArrayBufferMaxByteLengthOption(options).
[...]
1.1.5 GetArrayBufferMaxByteLengthOption ( options )
1. If Type(options) is not Object, return empty.
2. Let maxByteLength be ? Get(options, "maxByteLength").
3. If maxByteLength is undefined, return empty.
4. Return ? ToIndex(maxByteLength).
