Video Block : In HTML5 Source mode, video url previously correctly saved is replaced with the BigBuckBunny video on editor loading

[yucomds]

I'm adding a video. The video is in mp4 format and is saved online. The video is playable if i put the link in the bvrowser address bar.
So, I use the Video Block to insert this video in the editor. In the settings view I choose "HTML5 Source" mode then i paste my video url and save the work; All it's fine.

Later I open my editor again for changing other stuff on the same page, and .. ta-dah! the previously correctly saved video url is replaced with the default BigBuckBunny video.

I'm using grapesjs - 0.16.30 and the latest version of grapesjs-blocks-bootstrap4.

Any suggestion/support for this? Thanks!

It seems a problem in the initialize of the editor. I'm currently using gjs-components and gjs-style json data. If I use the raw html and css it works as expected.
