Incremental search wasn't working in the user interface section, fixed

Steps to Reproduce:

  1. Open Origam Architect

  2. Navigate to User Interface → Screen Sections → open any screen section (e.g. DimensionEntityRelation)

  3. Click on the Data Source dropdown

  4. Start typing to search for a specific data source

Expected: The dropdown list filters incrementally as the user types.

Actual: The full list of data sources was shown without filtering; incremental search had no effect.
