Primitive: Null deref in _collectAccessibilityElements on missing wrapper
Triage note: _collectAccessibilityElements added `if (!element) continue;` so a null wrapper/attachment/remote-frame element is not passed to [result.elements addObject:], preventing a null-object crash reachable from web-influenced AX tree structure.

Security-relevant, below the exploitable-grade bar for a full root-cause writeup. The triage verdict is above; the side-by-side patch is below.
