Describe the issue you are experiencing

Comments and commented parts of code in the frontend "code editor" are automatic deleted when I save the yaml code editor.

Describe the behavior you expected

Comments and commented parts of code in the frontend "code editor" are automatic deleted when I save the yaml code editor.

Steps to reproduce the issue

As a example I made a simple statistics line graph in the frontend dashboard.

Now I want to manually edit the yaml code with the "code editor".

In this example there a no layout-settings used. But when I am changing layout or something and I want to check the behavior of a setting I will comment # the lines. Or when there are multiple entities in a graph-card I wil sometimes make a note in the yaml.

So now I placed a comment in the yaml, and commented the min and mean of the card.

Now I used the "opslaan" button and then edit the card again. Now al the commented parts and notes are gone.

Now I used the statistics card as example, but this also happening with my plotly graph cards.
