Linked errors in Sentry js browser sdk are given incorrect title in Sentry

[johndoherty]

Environment

SaaS (https://sentry.io/)

Steps to Reproduce

Create a linked error in sentry in the browser:

try {
  // ...
} catch (e) {
    const fetchError = new Error(`Failed to fetch`);
    fetchError.cause = e;
    Sentry.captureException(fetchError);
}

Previously the title of the error in sentry would be: Failed to fetch, but now the title is whatever is in e.message.

Expected Result

Title of error in Sentry UI is the error thrown, not the message of the error in the cause field. In the example above it should be "Failed to fetch", instead of e.message.

Actual Result

Unfortunately I can't share what we see in our sentry UI publicly, but the title of the error that we see is e.message

Hi, @johndoherty - thanks for reporting! This is actually the same issue as #59679, so I'm going to close this in favor of that, since a bunch of conversation has already happened there. Feel free to comment if you have stuff to add. (Actually, I have a question for you, but I'm going to ask it over there so we can keep discussion in one place.)
