Summary: AX: Calling NSAccessibilityColumnsAttribute and
NSAccessibilityRowsAttribute simply to get column/row
count can be very expensive.
Product: WebKit
Version: 528+ (Nightly build)
Platform: Macintosh
OS/Version: Mac OS X 10.9
Status: NEW
Severity: Normal
Priority: P2
Component: Accessibility
AssignedTo: webkit-unassigned at lists.webkit.org

VoiceOver needs to query for column and row count often when navigating a table. When the table is large, this can be VERY expensive to do over and over. Given the dynamic nature of many tables (like Facebook, Twitter) we need a lightweight way to get the count out easily.
Such as:
NSAccessibilityColumnCountAttribute
NSAccessibilityRowCountAttribute
