QTimeZone IANA id broken on Android

QTimeZone behaves badly on Android. Windows works as expected:

auto z = QTimeZone("America/Los_Angeles");
qDebug() << z.id();    // Returns "Pacific Daylight Time"

auto z2 = QTimeZone(z.id());
qDebug() << z2.id();   // Returns "GMT"!!!

z.id() should return a valid IANA code ("Pacific Daylight Time" is not correct).

This worked on 5.12.6, so something broke since then.

Did not see any other reports of this in the bug database.
