Steps to Reproduce

Reported by a customer who has mentioned the following:
upgrading to Sentry JS V8 breaks the Square payment form (square.js) because they have this line in their code:

!!(t && t.__SENTRY__ && t.__SENTRY__.hub) && !qe(e).isOlderThan(Me) || Ve(e, new je),

And isOlderThan is no longer exposed in v8.
