Edit Response results in empty array (that leads to cf-conditional to fail)

[heri16]

On the first flow, the cf-conditonal works normally because tagValue is [''] (array with emtpy string).

However, if the user edit a response, the cf-condition fails to work and always return false because tagValue is now [] (emtpy array).

We are testing for emtpy string with a RegExp cf-conditional for a tag that might be skipped/hidden due to a previous tag.
