File upload limit affects multiple files instead single ones
Description
It appears that an upload of multiple files is not possible anymore when the combined size of all files is bigger than 10 MB. An attempt to upload files combined with more than 10 MB results in a 413 error warning (Request Entity Too Large). An upload of single images smaller than 10 MB still works without any problems.

We tested it and can confirm this issue with multiple files.
After looking into it, we discovered that the issue doesn't lie in our code, but in the flask components. We also tested an early version, 6.3.0., which has also this issue.
At the moment, we are not sure how to proceed. A temporary workaround would be to increase the file upload limit, which you can, because you are a manager. Just don't forget to set it back afterwards.

Since this is an implementation detail from Flask/Werkzeug, we cannot change it. Thank you for reporting, we updated the manual with a clarification. Sorry for the inconvenience, a short time solution is, to ask a manager to rise the file upload limit temporarily.
