Observed behavior

When I create a new exercise and I add images to the questions, then when I import the same exercise in Kolibri the images are not displayed at all.
Tested with a channel from production studio and it's working fine, so this is observed only on Hotfixes.

exercises.with.images.mp4

Expected behavior

The images should be displayed correctly.

Steps to reproduce the issue

1. Install the build from https://github.com/learningequality/kolibri/releases/tag/v0.18.3-beta0
2. Import the following channel from Studio Hotfixes: varik-faluk (https://hotfixes.studio.learningequality.org/en/channels/741fb8318bc745fcb97c70090917fb33/#/05502ad9656f477588506aba550c9138)

A fix for this has been merged to hotfixes - hopefully this should now be working as intended.

Hi @rtibbles, seems that this is partially fixed as if I have just inserted an image and not modified it in any way it will be displayed correctly in Kolibri but if I have inserted exactly the same image either in the body of the question or the answer and resized it then it's not displayed:

Thanks @pcenov, I suspect this is a totally different issue to the one I previously fixed, related specifically to the resizing. Will make a fix today.
