Help says "The following bindings may be internal" for non-existent names

[mcabbott]

After #50105, a warning about a name not being public is printed... even if the name does not exist at all:

help?> Base.no_such_name
  │ Warning
  │
  │  The following bindings may be internal; they may change or be removed in future
  │  versions:
  │
  │    •  Base.no_such_name

  No documentation found.

  Binding Base.no_such_name does not exist.

v1.10 just prints the last two lines, although only the last is really meaningful:

help?> Base.no_such_name
  No documentation found.

  Binding Base.no_such_name does not exist.

Thanks for the report!
