Rename on OS X with case insensitive file system

I created a folder in the project, named “A10”, filled it with files, then realized I had to rename it. Not to anything more useful, but to “a10”. There is something in the rename code that doesn’t just rename. In a shell “mv A10 a10” works, as does “mv a10 A10” to name it back. Komodo IDE 9 does this:

It is obvious that I can rename outside of Komodo, but I thought you guys should know about this behavior.
