Update: Further minimized example, the actual value of the constants is irrelevant, it seems the dependent where bounds are the primary issue.

It appears somewhere along the way, the playground link started working. Does this need a test, something in glacier, or any other work?

Remove `remap_env_constness` in queries

This removes some of the complexities with const traits. rust-lang#88119 used to be caused by this but was fixed by `param_env = param_env.without_const()`.
