Previously, "nested" time zone property bags were unwrapped up to one
level. That is, this object:
{
timeZone: {
// ...Temporal.TimeZone methods
}
}
would not be considered to implement the TimeZone protocol, but would have
its timeZone property used instead, if it were passed to an API that
required a TimeZone protocol object.
These nested property bags are no longer supported. Discussion:
