From 6af698fb81b9928c5d88c6bbca4b57229db1c2f3 Mon Sep 17 00:00:00 2001 From: Giteabot Date: Fri, 15 Dec 2023 11:04:37 +0800 Subject: [PATCH] Polyfill SubmitEvent for PaleMoon (#28441) (#28478) Backport #28441 by wxiaoguang Fix #28319 It only polyfills if there is no "SubmitEvent" class, so it has no side effect for most users.
