Bug ID: 262711
Summary: AX: AXIsolatedTree::updateChildren should not
updateNodeAndDependentProperties if children haven't
changed
Product: WebKit
Version: Other
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: Accessibility
Assignee: webkit-unassigned at lists.webkit.org
Reporter: tyler_w at apple.com

The intention of the updateNodeAndDependentProperties at the end of updateChildren was to update any properties that depend on AX children (of which there are many). However, we are doing this unconditionally, even when children don't change, which causes lots of wasted work.
