• Type: Regression Bug
• Status: Closed
• Resolution: Fixed
• Affects Version/s: Master
• Fix Version/s: 7.3.1 CE GA2, 7.3.2 CE GA3, 7.3.10 DXP GA1, Master
• Component/s: Application Security > OAuth2, Frontend Infrastructure
• Labels: None

• Git Pull Request: https://github.com/stian-sigvartsen/liferay-portal/pull/237

Steps to reproduce:

1. Navigate to OAuth 2 Administration
2. Edit Analytics Cloud and navigate to Scopes
3. Assert that the "Analytics Cloud" panel is expanded (revealing the assigned AC scopes)
4. Click to expand any other collapsed panel

Expected Result: The "Analytics Cloud" panel remains expanded

Actual Result: The "Analytics Cloud" panel collapses

p.s. The expected behavior is important to OAuth 2 administration because the Scopes page must load with multiple expanded to reveal all assigned scopes (instead of expanding them one by one, which would be onerous).
