Steps to reproduce:

1. Create a new project
2. Open Package Manager and install the Multiplayer Play Mode package
3. In the Editor toolbar, locate the "Default" dropdown next to the Play button
4. Click the "Default" dropdown
5. Observe the size of the dropdown menu

\\
Actual results: The dropdown window appears excessively tall, leaving a large amount of empty space below the single list item

Expected results: The dropdown height should match its content, showing only enough space for the listed items (e.g., one item should not have space for five)

\\
Reproducible with versions: 1.3.0-exp.1, 1.4.2, 1.5.0-exp.2 (6000.047f1, 6000.1.0f1, 6000.2.0a9)

Not reproducible with versions: 1.2.2 (6000.047f1, 6000.1.0f1, 6000.2.0a9)

Can't test with versions: 2022.3.61f1 (No Multiplayer Play Mode Package)

\\
Tested on (OS): macOS 15.5 (Silicon M4)

Notes:

• The dropdown height suggests space for ~5 items, but only one item is displayed.
• This may affect user experience or cause confusion when interacting with the dropdown.
