From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: mas_disable_remote_accessibility.patch
Disable remote accessibility APIs (NSAccessibilityRemoteUIElement) for MAS
build.
According to ccameron:
NSAccessibilityRemoteUIElement is unnecessary for Electron's use-case. We use it
for progressive web apps (where the AXTree is in the browser process, but macOS
needs to think it's coming from the PWA process). I think it can just be chopped
out -- if there are any side-effects, we should be able to work around them.
