Steps to Reproduce

const wat = new Error('this is very long message that should be truncated and will be, this is very long message that should be truncated and will be, this is very long message that should be truncated and will be, this is very long message that should be truncated and will be, this is very long message that should be truncated and will be');

wat.cause = new Error('this is very long message that should be truncated but wont be, this is very long message that should be truncated but wont be, this is very long message that should be truncated but wont be, this is very long message that should be truncated but wont be, this is very long message that should be truncated but wont be');

Sentry.captureException(wat);

This is usually apparent when using React with error boundaries, causing UI to look ugly.

Expected Result

Both exceptions should have their message truncated up to maxValueLength or default 250.

Actual Result

Only the first exception is correctly transformed.
