Is this about pinned tabs on iPadOS?

This particular bug is about Safari 12 on macOS. We did fix the bug in Safari 13 on macOS (and I am actually not able to reproduce this issue on Safari 13 on macOS).

Issue may remain on iPadOS 13 though but this would be a separate bug.

I might be wrong but I don't think we support pinned tabs on iOS.
