What happened?

Here in the manual: https://docs.mautic.org/en/5.x/builders/email_landing_page.html
is standing:

"GrapesJS gives you all the necessary tools you need to optimize your templates to look awesomely on any device. In this way you’re able to provide various viewing experiences. In case you require more device options, you can easily add them to the editor."

For e-Mail it works.

Landing Pages with GrapesJS are not usable. But look yourself:

I made a test from scratch with the GrapesJS Builder. Have some issues:

View on my monitor:

Smartphone View

View with embeded Video

The auto width function doesn't work.

Here are the options for videos. You see that it doesn't work.

Here are the options for images. Auto has no effect.

If this is repaired / improved, the new builder has many options, so that everyone can make easy a landing page for a funnel.

How can we reproduce this issue?

Embed a youtube video and a image with e.g. width of 1920px and you see that that it does not fit into the width.

If you need the link to my test landing page, please contact me.
