Reproduction steps:
1. Open user-submitted project
2. Open the "Test Scene" scene from the Assets folder
3. Enter Play Mode
4. Double-click on the "Row 1" item
5. Click on the "Row 2" item

Expected result: System.Collections.Generic.List`1[System.Object] is logged after double clicking on "Row 1" item
Actual result: System.Collections.Generic.List`1[System.Object] was logged only after clicking on "Row 2" item

Reproducible with: 1.0.0-preview.17, 1.0.0-preview.18 (2021.1.5f1, 2021.1.28f1), Built-in (2021.2.9f1, 2022.1.0b4, 2022.2.0a2)
Not reproducible with: 1.0.0-preview.17, 1.0.0-preview.18 (2020.3.27f1)
Could not test with: 2019.4.34f1 (UI Toolkit Package is unavailable), 1.0.0-preview.17, 1.0.0-preview.18 (2021.1.0a1, 2021.1.4f1) (error CS0117: 'FontEngine' does not contain a definition for 'TryGetSystemFontReference')

Notes:
- Couldn't find the exact regression point, because the issue couldn't be tested between 2021.1.0a1 - 2021.1.4f1, due to error CS0117: 'FontEngine' does not contain a definition for 'TryGetSystemFontReference'
- For package versions of UI Toolkit, use the attached project "DblClickTest_2" instead
