Steps to reproduce:

Open the attached "GenerateLights" project
Make sure "Use new Hierarchy window" is enabled in the Preferences
In the Hierarchy, select "Cube" GameObject
From the top Editor toolbar, select QA > Console > Log Warning For Selected
Click on the warning and observe the Cube gets highlighted in the Hierarchy
Drag some other tab (e.g. Scene) next to Hierarchy, so that the Hierarchy tab becomes inactive
Click on the warning again
Click on anything in the Scene view (though it seems to reproduce more by selecting "Cube")
Repeat 7-8th steps a few times if needed
Observe the Console

Actual results: "NullReferenceException: Object reference not set to an instance of an object" and "GUI Error: Invalid GUILayout state in view. Verify that all layout Begin/End calls match" errors are thrown. In 6000.6.0a5, no errors are thrown but multiple warnings are spewed with "Trying to access the DPI setting of a visual element that is not on a panel.".

Expected results: No errors are thrown or warnings are thrown.

Reproducible with versions: 6000.4.0b1, 6000.4.6f1, 6000.5.0b6, 6000.6.0a4, 6000.6.0a5

Not reproducible with versions: 6000.4.0a5

Tested on (OS): Windows 11

Notes:

The errors are then unselectable and are thrown until Hierarchy is an active tab gain
Seems to reproduce with any GameObjects when pinging them from Console (does not repro when pinging from Inspector)

Errors:

GUI Error: Invalid GUILayout state in ConsoleWindow view. Verify that all layout Begin/End calls match
UnityEditor.GUIView:ProcessEvent (UnityEngine.EntityId,intptr,bool&)

NullReferenceException: Object reference not set to an instance of an object
UnityEngine.UIElements.HierarchyV2.CollectionView.SetScrollingParameters (System.Double currentScrollOffset, System.Double maxScrollRange) (at <b9afe1042f904bddbedb2b58e5d083ab>:0)

Warnings:

Trying to access the DPI setting of a visual element that is not on a panel.
