Issue with classifying referring domain after 1.119.2

[benrobertsonio]

After I upgraded my to posthog-js version from 1.117 to 1.128.1, I noticed that insights broke down by referring domain suddenly started being dominated by my domain.

I grabbed a screenshot as an example:

You can see here that pageviews from colorbliss.art started spiking on the day that I upgraded to posthog-js@1.128.1. To test this, I downgraded to posthog-js@1.119.2 yesterday to see if that would change anything. You can see in the screenshot that www.google.com spiked and colorbliss.art dropped.

Not sure if others have experienced the same.

This is especially visible on events I capture around purchases, since 95% of those events now have no meaningful referral data.

I haven't yet narrowed down which version of posthog-js introduced the error. I've looked through the release log and didn't see anything obvious to me that looked like a fix for it either.

I can keep experimenting with versions, but just wanted to flag in case others are seeing the same.

Hey @benrobertsonio - could you try a recent version (>=1.149.0)? I believe #1314 should have fixed this

I've been on 1.148 for a few weeks and it seems much improved. Thanks for following up!

Great, thanks for letting us know!
