[Bug]: Node space calculation missing padding

### Frontend Version

1.19.0

### Expected Behavior

Nodes have the same amount of padding after the last widget

### Actual Behavior

Bottom padding on nodes can be tiny in certain configurations.

Low priority for now. Potentially DOM widget related. Or bool/toggle.

### Steps to Reproduce

This behaviour was seen in one of the nodes made last week; managed to repro whilst doing something unrelated.

1. Add standard CLIP loader
1. `graph.nodes[0].addWidget("toggle", "switz", true, () => {}, {})`
1. Observe lack of padding
