Fields in Action Properties require two clicks to focus when switching from another edited field

Reproduction steps:
1. Create a new project and install the Input System package
2. Right-click in the Project Window and select Create > Input Actions
3. Open the newly created .inputactions asset
4. Create a new Action Map
5. In the Action Properties, next to the “Processors”, click the + button
6. Select “Normalize”
7. Edit one of its fields (e.g. Min)
8. While that field is in edit mode, click on a different field (e.g. Max)
9. Observe the field

Expected result: The field is selected and in edit mode
Actual result: The field is not selected and only gets selected on the second click

Reproducible with: 1.12.0 (6000.0.36f1), 1.14.0, 1.15.0 (6000.0.59f1, 6000.2.7f1, 6000.3.0b4, 6000.4.0a1)

Reproducible on: Windows 11
Not reproducible on: no other environments tested

Note:

• Reproduces with “Normalize” and “Clamp” options under the “Processors” dropdown and under the “Interactions” dropdown when more than one editable field value is available (Could affect other fields as well)
