Tests that the Intl.DateTimeFormat constructor calls
|
||
OrdinaryHasInstance instead of the instanceof operator which includes a
|
||
Symbol.hasInstance lookup and call among other things.

info: >

||
ChainDateTimeFormat ( dateTimeFormat, newTarget, this )
|
||
1. If newTarget is undefined and ? OrdinaryHasInstance(%DateTimeFormat%, this) is true, then
|
||
a. Perform ? DefinePropertyOrThrow(this, %Intl%.[[FallbackSymbol]], PropertyDescriptor{
|
||
[[Value]]: dateTimeFormat, [[Writable]]: false, [[Enumerable]]: false,
|
||
[[Configurable]]: false }).
|
||
b. Return this.
