Steps to reproduce:

1. Create a new Unity project using a 3D Universal Template
2. From the Project window, open the "InputSystem_Actions.inputaction" asset
3. Create a new Action Map
4. Make sure the Input Actions Editor is not maximized and placed lower on the screen
5. In the Action Properties tab, click on the "" button next to Interactions
6. Add a few any properties until a scrollbar appears (e.g. "Hold", "Press")
7. In the Action Properties tab, scroll down and click on the "" button next to Processors
8. Observe the opened Processors dropdown

Actual results: The dropdown opens way above the “” button

Expected results: The dropdown opens right below/above or next to the “” button

Reproducible with versions: 6000.1.0a1, 6000.2.14f1, 6000.3.0f1, 6000.4.0a5, 6000.5.0a3

Not reproducible with versions: 6000.0.23f1, 6000.0.63f1

Reproducible on: macOS 26.1 (M1 Pro)

Not reproducible on: Windows 11

Notes:

• Does not reproduce if the Action’s “Action Type” is set to “Value” or “Pass Through” (Options in the Processors dropdown differ with different types)
• Could not reproduce with Windows so appears to be macOS specific
• The reproduction does not depend on the Input System package version
