Image fails to load with 403 after insertion

[max-nextcloud]

Describe the bug
After editing a new page and inserting a new image the image won't render and displays a 403 error in view mode:

To Reproduce
Steps to reproduce the behavior:

1. Create a new page in a collective
2. Insert an image
3. Click done
4. See failed image rendering with 403 error
5. Reload the page to see that the image upload was successful.

Expected behavior
Show the image right away.

Server details:

• local cypress run against current master
• cloud.nextcloud.com on 29.0.0.rc4

Failed network request

The failed network request actually seems to come before even inserting the image.

I noticed this while working on the Supports page content editing and switching to read mode pages spec. So it looks like we may have a failing test for it already.

This also affects 28.0.4.

Noticed the same behavior under 28.0.3 and 29.0.0

Could you please upgrade to 28.0.5 and 29.0.1 and see whether this still happens there? We shipped some related fixes with the latest releases.
