Required Field Validation: Several issues

Screenshot1:
When a required field in a compound is not filled in, it will also highlight the non-required fields in the compound
You can also see it highlights the entire compound.

Screenshot2:
When the compound is a multiple. When you do not fil a required field, it highlights the non-required fields in the compound, but now it does not highlight the entire compound.

Screenshot3a:
This is a complicated compound (with compounds inside compounds). When you leave the required fields open, the first three (non-required) fields are highlighted, and the rest only the titles are red.
But (screenshot3b) when you save again it will only make the required (empty) fields headers red.
