AX: Setting null on an ElementInternals ARIA reflection property should fully
clear any previous value
https://bugs.webkit.org/show_bug.cgi?id=307286
rdar://169929531
Reviewed by Anne van Kesteren.
When ARIA element reflection array properties (ariaControlsElements,
ariaDescribedByElements, etc.)
on ElementInternals were set to null, subsequently getting them returned an
empty array instead of
null. This was because setElementsForAttribute stored an empty vector in the
map when null was
passed, rather than removing the entry entirely.
