ResolveName will replace the subobject delimiter (colon) with two periods. This increases the length of the string, and can cause asserts due to the string exceeding NAME_SIZE even when the name was previously verified to fall within the allowed length.
1. Copy a string to clipboard that is less than 1024 (NAME_SIZE) characters long (such as 1023 characters) with many colons (23 colons should work for this test case)
2. Open a dropdown combo box in editor for selecting assets with a search bar at the top.
3. Note crash (or breakpoint at checkf statement if connected to visual studio).
