Memory leak and Crash on mono_gc_memmove_aligned when typing too many characters in the Shortcuts Profile naming text field

-

Sep 01, 2023

How to reproduce:
1. Open any project
2. Navigate to Edit > Shortcuts
3. Select a Profile
4. Select the same Dropdown Menu when selecting a profile and select "Rename Profile"
5. Start typing lots of characters (using ctrl+c and ctrl+v)

Reproducible with: 2021.3.29f1, 2022.3.7f1, 2023.1.9f1, 2023.2.0b8, 2023.3.0a4

Note: The text field has no character limit, as characters get added to the text field, memory usage drastically increases until the Editor crashes
