if we have website_path = ('', 'erp5', 'web_site_module', 'renderjs_runner')
path = ('++resource++zmi', 'bootstrap-4.6.0', 'bootstrap.bundle.min.js')

common_index will still be 0

so those codes are running
if path_len > common_index + 1:
  path = website_path + path[common_index + 1:]

finally path will be ('', 'erp5', 'web_site_module', 'renderjs_runner', 'bootstrap-4.6.0', 'bootstrap.bundle.min.js')
without ++resource++zmi
