Why does isfolder() returns true when the argument is a space character in Windows OS?

The isfolder() function with the space " " as parameters returns true in Windows. Ia this expected?

Windows treats " " as a relative path and then trims trailing spaces. Essentially it does something like this:

input = " ";

Since input is not absolute,

input = fl::filesystem::absolute(input)

which turns the input space into "C:/Users/temp/ "

Hence, Windows trims the trailing spaces which leaves "C:/Users/temp".

While this may seem unexpected, it is logically consistent with Windows behavior. If you replace " " with something like "folderWithTrailingSpace" then you will get the same behavior.
