Images are not shown properly in the PMI (project proposals)

Summary

Images of this draft of project proposal are not shown properly in the content of the proposal, however they are visible in the "edit" mode.

Steps to reproduce

Open the proposal draft. Select the Edit tab and see the images (inserted in the description section).

What is the current bug behavior?

Images are not shown after saving uploading them in the edit mode.

What is the expected correct behavior?

Images added in edit mode should be visible in the drafted proposal, or at least the user should be warned about the issue that is preventing the PMI to show the images.
