Scripting Tables - bug when resizing via JavaScript

Tables - can be ANY quantity / size:

This script - modifying ROWS:

app.activeDocument.stories.everyItem().tables.everyItem().rows.everyItem().autoGrow = false;
app.activeDocument.stories.everyItem().tables.everyItem().rows.everyItem().height = 2;
app.activeDocument.stories.everyItem().tables.everyItem().rows.everyItem().autoGrow = true;

Will return this:

LAST row in the LAST Table in EVERY Story will ALWAYS be higher than the rest:

But this - modifying CELLS:

app.activeDocument.stories.everyItem().tables.everyItem().cells.everyItem().autoGrow = false;
app.activeDocument.stories.everyItem().tables.everyItem().cells.everyItem().height = 2;
app.activeDocument.stories.everyItem().tables.everyItem().cells.everyItem().autoGrow = true;

Will ALWAYS return the correct result: 

Plain tables - no header / footer.
