But if we could make the table size correct before we call `prepareImports` then I think this would not be need here because we set the size of imported table based on the symbol information on line 1405.

I guess the problem is that we call `prepareImports` early on before the table size I known?     I wonder if we could change the ordering ot make this possible.
