debugStickyOffsetAuthorityMismatchCount property
Force-created sticky rows whose written parentData.layoutOffset
disagreed with the frame's structural authority
(_structuralOffsetAt) at the moment of the write. MUST be 0 on
every layout: the sticky block writes that authority, and this
write is the one place in performLayout that used to read a raw
_nodeOffsetsByNid slot for a nid the frame never wrote. Reset at
the top of performLayout.
Implementation
@visibleForTesting
int debugStickyOffsetAuthorityMismatchCount = 0;
