Repro Ratio: 6/6
Regression testing in //UE5/Release-5.0-EarlyAccess CL-16682836 since this feature wasn't in UE4. This issue did NOT happen.
This issue only seems to happen when the windows are docked to the sidebar and not when they are docked to the layout.
NOTE on logs: For comparison I uploaded two project logs. MyProject3 was the project that I imported all available packs and tried the browse in both layout docking and sidebar docking. the other project is only testing the world settings game mode while docked in sidebar.
Note on GIFs: The expected was done in Early Access so the Browse button does look a little different than what it does in Release 5.0.0. but the expected result should be the same.
Expected Result: World Settings tab collapses back into sidebar and Content Browser Expands to show the asset that is selected in the field
Actual Result: World Settings tab either stays open, or collapses back into sidebar and content browser is not Opened automatically. However, if you manually expand the content browser, you will see that the asset location is opened and the asset is highlighted.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-149309 in the post.
