"File is too big" error when uploading jpg

When I try to upload an image using the example module, it refuses to upload and shows an error saying the file is too big.

See https://www.drupal.org/files/issues/2017-06-07-filebrowsererror.png

As you can see here: https://www.drupal.org/files/issues/2017-06-07-filebrowser_field_setting... My php max size is set to 15 GB, and my field is set to allow 1GB uploads. This is on my laptop, so I keep the limits high...

I could find no configuration anywhere limiting the upload to 2mb. I checked php.ini, .htaccess, Drupal settings under config -> file system, etc.

Here are some details about my set up:
