Bug 126948 – AX: FrameSelection::notifyAccessibilityForSelectionChange() calling UAZoomChangeFocus with incorrect rectangle coordinates

• Status: NEW
• Component: Accessibility

[Susumu Harada]

* SUMMARY

In FrameSelectionMac.mm, FrameSelection::notifyAccessibilityForSelectionChange() seems to be calling UAZoomChangeFocus with incorrect rectangle coordinates.

* STEPS TO REPRODUCE

1. Enable zoom and zoom in.
2. Open Safari and size the window so that it is not full screen.
3. In the Safari address bar, type a letter (e.g., "w") that causes the suggestion dropdown to populate.
4. Type additional letters, until the size of the suggestion dropdown updates and changes size.
5. FrameSelection::notifyAccessibilityForSelectionChange should be called when the suggestion dropdown updates and changes size.
6. Monitor the value of cgViewRect and cgCaretRect when #5 happens.

* RESULT

The cgViewRect size seems to match the content view area size, but its position is pegged to the lower-left of the screen.
The position of cgCaretRect also seems to be pegged to the lower-left of the screen.
