How to reproduce:
1. Create a new project
2. In the Hierarchy, right-click -> Light -> Reflection Probe
3. In the Inspector, under the Reflection Probe Component, click "Modify capture position" 
4. With the tool selected, click "Bake"
5. With the tool still selected, in the preview, click three-dot menu -> Convert to Floating Window -> three-dot menu again -> Dock Preview to Inspector
6. Observe the Scene view

Expected results: The borders of the Reflection Probe are visible
Actual results: The borders of the Reflection Probe are not visible unless the Reflection Probe is reselected

Reproducible with: 6000.0.57f1, 6000.1.16f1, 6000.2.2f1, 6000.3.0b1

Reproducible on: Ubuntu 24, macOS Sequoia 15.6 (M1)
Not reproducible on: No other environment tested

Notes:
- For the better reproduction results, it is better to create a new Reflection Probe and repeat the steps after reproducing the issue once. Even though the issue can be reproduced multiple times, it seems to be most consistent only for the first time
- The bug can be also reproduced by changing pr simply clickling different values in the Inspector, but from the observation, the mentioned method is the most consistent
- Reproducible with both editing tools selected
- If the issue is not reproduced with the Preview, click aroudn the values for a while, toggling the "HDR" seems to be consistent too
