Since Magento 2.3 the wysiwyg image uploader incorrectly uses pub/media as storage root.

[hostep]

Preconditions (*)

1. Magento 2.3.1 or 2.3-develop (I've used commit d3fdecf, can't use the latest commit 28757e4 since it breaks the backend due to some 'unserialize' warnings)
2. PHP 7.1.27

Steps to reproduce (*)

1. In the backend go to Content => Pages
2. Click 'Add New Page'
3. Expand the 'Content' section, click 'Show / Hide Editor' and click 'Insert Image...'

Expected result (*)

1. The Storage Root being represented by pub/media/wysiwyg
2. (screenshot is from 2.2-develop)

Actual result (*)

1. The Storage Root being represented by pub/media
2. 

Discussion

I think this is incorrect in Magento 2.3.x, as it would allow non-technical users to delete/change files they probably shouldn't touch. For example I was perfectly able to just remove the pub/media/catalog directory using this interface, which is not a really good idea ...
