Bug ID: 190235
Summary: IntersectionObserver doesn't keep target's JS wrapper
alive
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: Layout and Rendering
Assignee: webkit-unassigned at lists.webkit.org
Reporter: rniwa at webkit.org

When an element is enqueued as an IntersectionObserverEntry and subsequently removed from the document,
there is no way for JSC GC to know the JS wrapper of the element needs to be kept alive.
As such, the JS wrapper of an element can be erroneously collected.
