I would first check m_coreObject and do the early return, after that we know
that it will not be null and avoid checking it again. I am thinking of this:

  if (!m_coreObject)
      return map;

  m_coreObject->updateBackingStore();
  auto* document = m_coreObject->document();
  // ...rest of the code as it was...

> Source/WebCore/accessibility/atspi/AccessibilityObjectDocumentAtspi.cpp:148
> +            return { };

Same here, there are two null-checks on m_coreObject one right after the other.

This is because updateBackingStore can make m_coreObject nullptr.

Same here, the pattern is repeated everywhere.
