From 43859d47e14b1e4b484b9534fd4469f270032494 Mon Sep 17 00:00:00 2001 From: Alexey Shvayka Date: Mon, 11 Sep 2023 07:04:16 +0100 Subject: [PATCH] Align window.opener setter reconfiguration behavior In particular, if it fails to reconfigure the property, it should throw a TypeError. Previously it was specified to return a boolean, which was clearly incorrect. --- source | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/source b/source index 9dc10de3700..e4aed77eb44 100644 --- a/source +++ b/source @@ -2972,6 +2972,7 @@ a.setAttribute('href', 'https://example.com/'); // change the content attribute
