Summary:
There's a bug in the network inspector.
Messages come in in batches for performance reasons.
These batches can include both requests and responses, but the code assumes only one or the other.
This fixes it to make it not mutually exclusive.
This bug only affects row building in the table, so when you click on the row, you can still see the response and everything.
