Enfold Child: editor-style-shared.css not applied in page builder and editor

Hi
I want to create a custom style for my customer. Something like this:

.myquote {
  color: #b01634;
  font-size: 20px;
  font-weight: bold;
  text-align: center;
}

I am using a child theme and saved this css into editor-style-shared.css.
The style is applied to the website user, but not to the editor. It is not visible in pagebuilder nor in the editor.

Am I missing something?
Btw. Your Enfold theme is outstanding!!
