Method parameter tooltip offers wrong class

When mousing over a parameter type declaration, the tooltip offers up an unrelated class; not reachable by current package and imports and misses the correct class which is declared in the current file/class.

The issue names no source file, test, or entry point. Reproduce the parameter-type hover shown in the report, then trace how the tooltip resolves classes against the current package, imports, and current file or class; done when it offers the reachable class declared there instead of the unrelated class.
