Discovered while testing MDLQA-17741 by community user and confirmed by myself (with varying levels of error).

Follow the setup to configure your server with upload and post limits found in the issue MDLQA-17741.

Follow the set of steps, but pay attention to the steps where you upload a file larger than the server allows.

User1 = Teacher (respects upload limit of 1mb)
User2 = Admin (no upload restrictions)

Small file was ~190kb
Large file was ~1.9mb

My dev environment has the server setup with PHP 8.1 and 

• post_max_size = 1M
• upload_max_filesize = 1M
  There are 3 types of upload the test covered:

1. Drag and drop
2. Upload a file
3. Using an existing file repository (moodledata/repository/xxxxxx)

Step #14 fails with spinning wheel (user1, upload file, large file).

Step #20 soft-fails with a different message than expected, but it is in the same spirit (user1, file repo, large file).

Step #35 fails with spinning wheel (user2, upload file, large file).

Step #28 fails with a different message than expected (user2, drag and drop, large file).{}

Main issue is that we are not receiving any feedback on steps #14 and #35 (using the 'Upload a file' in the file picker). This is directly linked to the limitation of post_max_size in the php.ini file.
