Steps to Reproduce

1. Open the API reference.
2. Click the 400 response to expand it.
3. Also expand the properties of the error object
4. Click a blank area on the page.

Actual UI Behavior

• Error response is unexpectedly collapsed. All of its nested properties that were previously expanded are also auto-collapsed.
• Error response example is auto-replaced with success response example.

Expected UI Behavior

• Error response accordions stay expanded until the user explicitly collapses them.
  • I suggest not auto-collapsing errors even if the user expands another error - to reduce unnecessary interaction costs.
• (Optional) Response example snippet continues displaying the error response, unless the user clicked within the content area of success response description.
