isAccessibilityFocusable

Determines whether this element receives individual TalkBack focus, or gets absorbed by an ancestor.

Based on TalkBack's shouldFocusNode() logic, which combines two concepts:

• isActionable: clickable/longClickable/focusable or has those actions

• isSpeakingNode: has text/contentDescription, or has non-focusable speaking descendants

Actionable nodes always get focus. Speaking-but-not-actionable nodes get focus only if no speaking ancestor above them would absorb their content. Scrollable containers never get focus themselves.
