Thanks! I have one nit and one suggestion. After that, it's good to go. Lastly, could you update the PR title to something more descriptive? It's pretty general right now.

I think it would be better to split this test file or to move it somewhere else since it not only contains non_lifetime_binders but also closure_lifetime_binder (tests for the latter are usually placed in tests/ui/closures/binder). Note that there already exist tests for for<T> Trait<T> as well as for for<T> || -> (), maybe you can extend them instead of creating new files (you can add a comment above the new test cases in the form of // Regression test for issue #NNN)?

Also the name of this test isn't super descriptive, maybe call it bounds-on-type-binders.rs (for NLB) and bounds-on-closure-type-binders.rs (for CLB)?

Thank you.
According to the suggestion, split it into two files.
