Focused input field from the "Agents" tab gets drawn in the "Areas" tab when switching tabs in the Agent Settings window

Steps to reproduce:

1. Create a new 3D URP project
2. In the Hierarchy, right-click > AI > NavMesh Surface
3. Click on the "Humanoid" dropdown next to the "Agent Type" property
4. Click "Open Agent Settings..."
5. Click on any input field (e.g. Humanoid) in the Agents tab
6. Switch to the "Areas" tab
7. Observe the fields

Actual results: The input field value that was focused in the Agents tab gets drawn in the Areas tab, in an unrelated row. It stays there until clicking elsewhere in the window

Expected results: The input field is not drawn in the Areas tab after switching tabs
