Conditional oneOf options for select field are not rendered

[denatys]

In v1, a select field (uom) that relies on conditional oneOf definitions inside allOf (if/then) renders without any options.
The same schema worked correctly in v0.

Expected Behavior

When:
• type = "service" → uom select should display service-related options
• type = "goods" → uom select should display goods-related options

The dropdown should dynamically populate based on the selected type.

Actual Behavior (v1)

The uom field renders as a select input, but:
• No options are visible when the dropdown is opened
• The field is required, but user cannot select any value
