Reproduction steps:
1. Open the attached “BugRepro” project
2. Open the “Assets/Scenes/SampleScene“ Scene
3. Open the Memory Profiler window (Window > Analysis > Memory Profiler)
4. Build and Run the project (File > Build and Run)
5. Attach the Memory Profiler to the launched Player
6. In the Memory Profiler, capture a memory snapshot
7. After about 15 minutes, capture another snapshot
8. Select the captured snapshot and select All Of Memory
9. Find the “UnityEngine.InputForUI.Event[]“ script memory usage (Managed > Managed Objects > UnityEngine.InputForUI.Event[])
10. Find the same script memory usage in the memory snapshot from step 6
11. Compare the memory usage values

Expected result: The memory usage of the script did not increase
Actual result: The memory usage of the script increased and continues to increase

Reproducible with: 1.8.0-pre.2 (2023.2.5f1, 2023.3.0b1), 1.7.0 (2023.2.5f, 2023.3.0a14), 1.6.1 (2023.2.0b1)
Couldn't test with: 2021.3.34f1, 2022.3.17f1 (UnityEngine.InputForUI script was only added from 2023.2.X forward)

Reproducible on: Windows 11
Not reproducible on: No other environment tested

Note: The speed, at which the memory usage of the script increases, varies
