The isEmpty() check here is redundant but I hate that operator[] API returns a null character for invalid indices so let's not even care about that.

> Source/WebCore/Modules/entriesapi/FileSystemEntry.cpp:67
> +void FileSystemEntry::getParent(ScriptExecutionContext& context, RefPtr<FileSystemEntryCallback>&& successCallback, RefPtr<ErrorCallback>&& errorCallback)

If we have neither successCallback or errorCallback, we could just early return here, no need to do work. Silly that the API allows this at all.

This is not covered by the layout tests.
