Doesn't provide options for Entity Reference fields within and Inline Entity Form

This module is an extraordinarily useful work of art on a multi-value Entity Reference field!
Until that is, you choose to edit the field contents using the Inline Entity Field (IEF) → module.

When using the IEF, the options...

• Lock previous value
• Hide previous value
• Disable reorder
• Hide "Add more" button
• Hide "Remove" button
• Remove table header

...don't appear on the file editing form.

In your into you say that it supports fields: if field widget "multiple values" behavior value FIELD_BEHAVIOR_DEFAULT and I wondered why that wouldn't still apply when an Entity Reference is embedded within an IEF widget?

Can this be addressed via a minor alteration?
