Adaptive Probe Volume “Open” button closes the existing RPAsset window and opens a new RPAsset window instead of focusing the existing RPAsset window

Steps to reproduce:

1. Create a new Unity project using the Universal 3D template
2. Create a new Adaptive Probe Volume GameObject (GameObject > Light > Adaptive Probe Volume)
3. Press the "Open" button in the Inspector window under the Adaptive Probe Volume component
4. Dock the opened RPAsset window
5. Repeat step 3
6. Observe the RPAsset window

Actual results: The existing RPAsset window is closed and a new RPAsset window is opened

Expected results: The existing RPAsset window is focused instead of reopening

Reproducible with versions: 6000.0.59f1, 6000.2.7f1, 6000.3.0b4, 6000.4.0a1

Tested on (OS): MacOS Silicon Sequoia 15.6.1

Notes:

• All the other windows focus the existing window instead of closing the existing window and reopening a new window
