Tests that the Intl.NumberFormat constructor calls
|

OrdinaryHasInstance instead of the instanceof operator which includes a

Symbol.hasInstance lookup and call among other things.

ChainNumberFormat ( numberFormat, newTarget, this )

1. If newTarget is undefined and ? OrdinaryHasInstance(%NumberFormat%, this) is true, then

a. Perform ? DefinePropertyOrThrow(this, %Intl%.[[FallbackSymbol]], PropertyDescriptor{
|
||
[[Value]]: numberFormat, [[Writable]]: false, [[Enumerable]]: false,
|
||
[[Configurable]]: false }).
|
||
b. Return this.
