The site is using the ShareThis widget, which is being blocked. We would presumably need to yellowlist it, similarly to how we might deal with the AddThis widget.

This issue affects Desktop as well and it's still reproducing. I could reproduce this issue on macOS 13 with Nightly 140.0a1.
Note: The issue is reproducing with Standard mode in PBM as well.
