Bug ID: 247380
Summary: Check for execution context between different phases
of event listeners
Product: WebKit
Version: Other
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: DOM
Assignee: webkit-unassigned at lists.webkit.org
Reporter: chirag_m_shah at apple.com
Event listeners can move a frame, which invalidates the current script execution context between phases.
Basically, we should be checking for script execution context between:
fireEventListeners(event, EventInvokePhase::Capturing);
and
fireEventListeners(event, EventInvokePhase::Bubbling);
in EventTarget.cpp
