✅ Chart doesn't show up correctly in layout option preview after editing

[sosiology]

Describe the bug
Sometimes charts are not rendered correctly in the layout step, if the user goes back and forth between the layout step and the editing mode.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'test.visualiuze.admin.ch'
2. Select any data set and create a chart and duplicate it
3. Proceed to layout options, select Dashboard and Free Canvas and charts are rendered correctly
4. click the "back to editing" and add a new chart with a different data set
5. Proceed to layout options and see that the newly added chart is not rendered correctly

Expected behavior
I would expect to be able to move freely between the layout steps and editor mode, and have charts rendered correctly
