Renaming folders with dots in name treats them as file with extension

[Rick Kerkhof]

Files thinks folders should be treated like files when renaming.

Reproduce:
- Create a folder names "a.folder.with.many.dots"
- Right click it and choose Rename
- Only the part before ".dots" gets selected, thus Files thinks ".dots" is the extension of the folder(?!)

How would it know the difference between 'a.file.with.many.dots' and 'a.file.with.many.dots.dxf'?

Because it can check if the folder it is editing is actually a folder before handling it like a file.
