How to reproduce:

# Open or create any project
# Open the Unity Bug Reporter window (Help > “Report a Bug...”)
# Type a dot symbol (".") in the “Details*” section and press the Spacebar
# Observe the “Details*” section

Expected result: Space appears after the dot symbol right after pressing the spacebar
Actual result: Space does not appear after the dot symbol

Reproducible in: 2021.3.34f1, 2022.3.17f1, 2023.2.7f1, 2023.3.0b4

Reproduced on: MacOS 13.5.2 (M1, 2020)
Not reproduced on: Windows 11 Pro

Notes:

* Space appears after pressing the spacebar twice
* The issue is also reproducible in the “Title*” section
* This is MacOS-specific (or at least you cannot reproduce on Windows)
* To delete the “.“ after pressing the Spacebar once, you have to press backspace twice as well
