Comment (by soulseekah):

 Didn't think I'd ever encounter this, but I just saw this happen on a
 migrated client site via a call to `wp_upload_dir` from Divi theme, where
 the `et_images_temp_folder` option was not replaced correctly.

 An incorrect/badly formed `upload_path` would also get into an infinite
 loop. So this is not a theoretical scenario, this actually happens :(

 Patch got rid of infinite loop in `wp_mkdir_p` call.

 Any ideas on how to automate test for this? Or can this be merged without
 unit tests due to it being so dangerous to test?
