When bypassing a subgraph, the outputs of the subgraph always correspond to the inputs on the same line as this output, even if the nodes inside the subgraph are completely disconnected and unrelated.

### Prerequisites

- [x] I am running the latest version of ComfyUI
- [x] I have custom nodes enabled

When bypassing a subgraph, the outputs of the subgraph always correspond to the inputs on the same line as this output, even if the nodes inside the subgraph are completely disconnected and unrelated.

Reproduce the issue in the ComfyUI frontend with custom nodes enabled by bypassing a subgraph whose internal nodes are disconnected. Trace the subgraph bypass handling and compare each output with its corresponding input; done means outputs follow the relevant internal connections instead of always using inputs on the same line.
