Bug ID: 280874
Summary: Don't use page tiles for site-isolated root frames
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

<iframe>s don't create an implicit set of page tiles, they only get tiling sub-layers as needed based on size.
Currently with site-isolation, and cross-origin <iframe> (a 'root' frame) is getting page tiles, which will use more memory than is necessary.
