The manual test steps table in the execution screen appears empty

in a manual test, in a step definition, if the "data" field contains the text bellow... then when executing the test, the test steps list appears empty.
please find attached the firebug debug, which may indicate that the javascript code inside of the test step "data" field is being interpreted..
