[Bug]: Rivet screen blanks out; Uncaught RangeError: Maximum call stack size exceeded

### What happened?

While using a project with 16 subgraphs for awhile during a single session, I've occasionally had the Rivet application screen go completely blank (gray) when right-clicking on the Graphs area to create a new Subgraph. After this, I cannot save the project or do anything with the UI.

In the F12 console, I found "Uncaught RangeError: Maximum call stack size exceeded".

### What was the expected functionality?

UI should not go blank.

### Describe your environment

Windows 11
Node v20.11.1
Rivet 1.7.12

### Relevant log output

Reproduce the issue in the Rivet UI by using a project with 16 subgraphs, waiting during a session, and right-clicking the Graphs area to create a new Subgraph. Start with the F12 console and the reported RangeError; done means the screen stays usable and the project can still be saved.
