CREATE OR REPLACE PACKAGE BODY sentence can't be split in two lines. (4319745)

If sentence
CREATE OR REPLACE
PACKAGE BODY
is used instead of sentence
CREATE OR REPLACE PACKAGE BODY
then the Editor shows questions marks and is unable to compile.

When running the first sentence (in two lines), the follow error appears:
ORA-04050: invalid or missing procedure, function, or package name
- or -
ORA-00900: invalid SQL statement
- or -
ORA-24344: success with compilation error.

However, the second sentence (in a single line) works.
