Bug ID: 173329
Summary: Should media query callbacks be fired asynchronously?
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: Layout and Rendering

Test case
Currently Document::evaluateMediaQueryList() fires then synchronously through FrameView::layout. Since the callback could run any JS code, we might not be able to recover from it when climbing back on the callstack with nested frames.
See attached testcase (run-webkit-test --debug -1)
