Very strange. In that case, what is the type of data.buffer? The main SharedArrayBuffer is always created in the main thread during startup. Later growth does not create a new SAB in another thread, it just grows it, and it updates the views in each thread using updateGlobalBufferAndViews. Regardless, the buffer of those views must always be an SAB - if somehow it is just an AB, that would be a serious browser bug (which is possible, of course).
