Bug: image filename with + breaks on upload

Uploading an image with a '+' in the filename gives a HTTP 403 error.

Steps to reproduce:

  1. In page builder image field, click add or replace image and the media selector pops up
  2. Drag and drop an image with filename 'a+b.png'. A correct preview of the image appears. Watch for the upload to complete without error
  3. The image preview disappears. The image source that is now downloaded from the server gives a 403 forbidden HTTP status

Uploading the same image with any other name works just fine. Came across this because I was downloading images from our Legacy Prismic site and re-uploading to new slice machine repository; there spaces in file names have been swapped with plus signs.

Hi @glenn, thanks for raising this issue. The team will take a look at it this week and we'll update this thread once it has been fixed.
