Issue Description
A strange case - when running npm run lint on this sample repo, the no-misused-spread rule crashes with the following error:
Oops! Something went wrong! :(
ESLint: 9.19.0
TypeError: Cannot read properties of undefined (reading '0')
Occurred while linting /Users/benj-dobs/Documents/tseslint-repro/index.tsx:6
Rule: "@typescript-eslint/no-misused-spread"

There seems to be something about the StyleSystemObject type that causes the rule to crash. I haven't been able to reproduce this with simple types.
