Case-sensitivity of path_display with renamed parent folder

Hello, 

I am using the Python dropbox SDK and I encounter a problem when modifying the case of directories that have already been declared (same name but different case) in the past. 

For example, going from a dir:

/testdir/NewTest

To the same renamed one (only the case is modified):

/testdir/nEWtEST

After this kind of renaming, when listing the files with dbx.files_list_folder, the FolderMetadata of the renamed folder is OK (attribute path_display is correct), but the FileMetadata (and FolderMetada if any) of the subfiles (and subdirectories) are NOK: attribute path_display keep writing the name of the parent folder (the one that has been renamed) with the wrong case.

For example: 

/testdir/NewTest/subfile.txt

Instead of:

/testdir/nEWtEST/subfile.txt

Complete code to reproduce the problem:

import dropbox
dbx = dropbox.Dropbox(TOKEN)

# create test dir
path_1 = '/testdir'
dbx.files_create_folder(path_1)

# create a subdir and upload a file in this sub dir
path_2 = '/testdir/NewTest'
dbx.files_create_folder(path_2)

dbx_file_path = '/testdir/NewTest/file.txt'
with open(local_file_path, 'rb') as local_file:
    dbx.files_upload(f=local_file.read(), path=dbx_file_path)

# list content of test dir
lfr = dbx.files_list_folder(path=path_1, recursive=True)
print(lfr.entries)

# Gives 3 entries with correct spelling of path_display: 
# FolderMetadata(name='testdir', path_lower='/testdir', path_display='/testdir'),
# FolderMetadata(name='NewTest', path_lower='/testdir/newtest', path_display='/testdir/NewTest'),
# FileMetadata(name='file.txt', rev='73d511ef48f', size=8, path_lower='/testdir/newtest/file.txt', path_display='/testdir/NewTest/file.txt')

# Then delete and recreate subdir under a new name, and re-upload file
dbx.files_delete_v2(path=path_2)
renamed_path_2 = '/testdir/nEWtEST'
dbx_file_path2 = '/testdir/nEWtEST/file2.txt'
dbx.files_create_folder(renamed_path_2)
with open(local_file_path, 'rb') as local_file:
    dbx.files_upload(f=local_file.read(), path=dbx_file_path2)
    
# list content of test dir
lfr = dbx.files_list_folder(path=path_1, recursive=True)
print(lfr.entries)

# Gives 3 entries with correct spelling of path_display for the FolderMetadata but not for the sub FileMetadata: 
# FolderMetadata(name='testdir', path_lower='/testdir', path_display='/testdir'),
# FolderMetadata(name='NewTest', path_lower='/testdir/newtest', path_display='/testdir/nEWtEST'),
# FileMetadata(name='file2.txt', rev='741511ef48f', size=8, path_lower='/testdir/newtest/file2.txt', path_display='/testdir/NewTest/file2.txt')

# Try the same with double rename subdir with uppercase
renamed_path_aux = '/testdir/NEWTEST2'
renamed_path_2 = '/testdir/NEWTEST'
dbx.files_move_v2(from_path=path_2, to_path=renamed_path_aux)
dbx.files_move_v2(from_path=renamed_path_aux, to_path=renamed_path_2)

# list content of test dir
lfr = dbx.files_list_folder(path=path_1, recursive=True)
print(lfr.entries)

# Gives 3 entries with incorrect spelling (still the same problem): 
# FolderMetadata(name='testdir', path_lower='/testdir', path_display='/testdir'),
# FolderMetadata(name='NewTest', path_lower='/testdir/newtest', path_display='/testdir/NEWTEST'),
# FileMetadata(name='file2.txt', rev='749511ef48f', size=8, path_lower='/testdir/newtest/file2.txt', path_display='/testdir/NewTest/file2.txt')

PS: I read after typing that the problem was known and assumed for API v1. But with API v2, it seems that the problem does not concern anymore the whole attribute path_display, but only the parent folder that have been renamed (as we can see in the above first list, where the case sensitivity works well for parent folder : path_display='/testdir/NewTest/file2.txt')

Thank you for your support.

Are you planning to correct this behavior?
