• I am using the latest SDK release https://github.com/getsentry/sentry-javascript/releases

Reproduction Example/SDK Setup

Steps to Reproduce

User "dead clicked" a tel:-link, containing a real phone number.

Expected Result

The phone number should be scrubbed, since phone numbers are generally PII(?)

I understand that we can manually do this scrubbing in beforeSend, but it seems like a generic issue.

Actual Result

@jgarplind thanks for reporting this one as well.

@s1gr1d one more for PII

This is a bit trickier because it makes masking dependent on the attribute value 🤔 But it should be doable in maskAttribute, if it is an <a> element and a href attribute to check if it starts with email or tel to mask it 🤔
