Access directories which look like files on Mac

Question

I am creating a script for Chrome browser to handle files (using File System Access API). This is totally fine on Windows, but on MAC I have this issue:

The files are stored in folders which look like files on MAC. For example folder name is thisisfolder.xyz and inside there are files like file.xml.

thisisfolder.xyz
  file.xml
  file2.xml
  ...

If I choose directory handler (handle.getDirectoryHandle(someDirectory)), those folders (thisisfolder.xyz) are greyed out and can't be selected. If I choose file handler (handle.getFileHandle(someDirectories)), I can select thisisfolder.xyz and similar, but later when I want to access files in this folder, I can't, because API thinks those folders are files.

var subdirHandle = await handle.getDirectoryHandle(someDirectory);

for await (var [name, entry] of subdirHandle.entries()) {
    ...
}                                   

Do I have any possibility here?

This is working as intended. If you try to create a folder named test.txt on a Mac, the Finder even helpfully warns you about the issue you are experiencing:

Are you sure you want to add the extensions ".txt" to the end of the name? If you make this change, your folder may appear as a single file.
