## 🐛 Bug fixes

- #3867: Fixed a regression introduced in 1.1.0 where isinstance() narrowing of a union variable
silently stopped working when an earlier sibling branch in the same if/elif/else chain narrowed
a different variable with isinstance() and returned. The later narrowing left the union
untouched, producing false missing-attribute errors on code that checked correctly in 1.0.0.
