ALLOW_POPUPS_TO_ESCAPE_SANDBOX constant
Sandbox
const ALLOW_POPUPS_TO_ESCAPE_SANDBOX
Lets the sandboxed document open new windows without those windows inheriting the sandboxing. For example, this can safely sandbox an advertisement without forcing the same restrictions upon the page the ad links to.
Implementation
static const ALLOW_POPUPS_TO_ESCAPE_SANDBOX = Sandbox._internal(
'allow-popups-to-escape-sandbox', 'allow-popups-to-escape-sandbox');
