Reproduction steps:
1. Open the attached “IN-102260_LIVE-unity-test.zip“ project
2. Open the “Assets/Scenes/CityMap.Unity“ Scene
3. Using “WASD” walk next to the NPC in the bottom right
4. Open the chat in the game by pressing “Space” near the highlighted character
5. Using the Mac IME, type any Japanese text in the text field, without sending it/hitting Enter.
6. Attempt to delete text in the field using the delete/backspace key

Expected result: Each character is deleted one by one
Actual result: Characters don't delete right away, delete in chunks, or the text field becomes "stuck"

Reproducible with: 6000.0.50f1, 6000.1.6f1, 6000.2.0b4
Couldn’t test with: 2022.3.63f1 (Unable to downgrade)

Reproducible on: M1 Max MacOS 15.1.1
Not reproducible on: No other environment tested

Note: If the chat gets “stuck“, closing and reopening the chat shows the text from the previous session when trying to type, even though closing the chat should clear the text field
