Body editor not updating when switching between requests after Postman import

Environment:

• Yaak version: 2025.9.0-beta.9

• OS: macOS

Steps to reproduce:

1. Create a Postman collection with multiple POST requests, each with different JSON bodies

2. Import the collection into Yaak (File → Import)

3. Click on different requests in the sidebar

Expected behavior: Each request should display its own unique body content in the JSON editor.

Actual behavior: When switching between requests, the body editor does not update properly. It either:

• Shows the same body for all requests

• Shows the body from a previously selected request

• The body panel appears stuck/cached

Notes:

• The URL and request name update correctly in the header

• Only the body editor content fails to refresh

• This happens with both native Postman imports and Yaak-format imports
