Any error caught during a React component render or lifecycle method
will now be caught by the top-level error boundary, which shows the
user this new error page. The error page will display a simple error
message, and will show the details of the error in a collapsible
section.
The caught error is also reported to Sentry.
In development the error will be re-thrown to make it easier to see on
the console, but it is not re-thrown in production.
