In map constructor advanced labels do not update

User experience is flawed in map constructor when using "Advanced labels".

Steps to reproduce:

1. Create new map
2. In map "properties" mark Advanced labels and set Host label type: label
3. Save map
4. In map constructor add a "map element"
5. Change "Type" into "Host" (choose a host)
6. Click "Apply"

Result:
Map element label is not updated. Label remains an "Image"
Expected:
Label should update and give user a feedback, indicating that changes has taken effect.
