Field with depends_on condition non satisfied (hidden), required, triggers validation error (collective.easyform 3.2.1, Plone 5.2.14)

[fabiSwDevBeg]

Problem

When a field has a depends_on condition that is not satisfied (so the field is hidden), and the field is marked as required, the form still raises a validation error for that hidden field.

This makes it impossible to submit the form, even though the field is not visible to the user.

Steps to reproduce

1. Create an EasyForm.
2. Add a field fieldA (e.g., a checkbox or select) that controls visibility of another field.
3. Add a required field fieldB, and configure its depends_on condition to only show when fieldA is true.
4. Leave fieldA unchecked (so fieldB stays hidden).
5. Submit the form.

Expected behavior:
Form should submit successfully, since the hidden field fieldB is not shown to the user.

Actual behavior:
Form raises a validation error:
