macOS

### Expected Behavior

`error.message` shouldn't be prefixed with "Uncaught Error:"

### Actual Behavior

`error.message` is prefixed with "Uncaught Error:" when an error is thrown in a function defined in the preload script and caught in the renderer process. This only happens when `contextIsolation` is enabled.
