Setting Only lift Z below to 0 meant that this option is disabled, ZHop would be active at any layer height above what Only lift Z above was set to. This is explained in the tooltip also:
"If you set this to a positive value, Z lift will only take place below the specified absolute Z."

This option was lost, setting Only lift Z below to 0 resulted in no ZHop at all.

This PR brings back the old behaviour, nothing less, nothing more.
