            Bug ID: 238463
           Summary: AX ITM: Don't queue objects for removal if we bail
                    early in AXIsolatedTree::removeSubtreeFromNodeMap
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal

In both places we call AXIsolatedTree::removeSubtreeFromNodeMap(AXID axID, ...), we unconditionally remove queue axID for removal in AXIsolatedTree::queueChangesAndRemovals.

However, this is sometimes wrong, since AXIsolatedTree::removeSubtreeFromNodeMap can return early without removing axID. We shouldn't be queueing this object for removal in this case.
