Search for references to fields {typename}.* finds tons of wrong potential matches

See: https://bugs.eclipse.org/bugs/show_bug.cgi?id=425407

master, BETA_JAVA8, at least back to 3.6.2. Could be a variant of bug 423409.

A search for references to fields {typename}.* finds tons of wrong potential matches:

• Import > Plug-ins and Fragments > Binary projects:
  Choose org.eclipse.jdt.core and org.eclipse.core.commands

• Search > Java...:
  For "org.eclipse.jdt.core.dom.QualifiedName.*", Fields, References, Workspace

=> Finds completely inexplicable potential matches like "@see #describe" in > org.eclipse.core.runtime.content.IContentDescriber#getSupportedOptions()

This also happens if everything is in source.
