Gjs(MJML) can't see content formatted using Ckeditor

[VanoAkofashvili]

Hi there,
I'm using the grapesjs-mjml plugin to build email templates. The user can add custom variables in mj-text by focusing it and selecting a variable from the trait, which will take the variable and append it as a child to the component like this:

 onEvent({ component, event }) {
        const selectedTag = (event.target as HTMLInputElement).value
        component.append(`{{${ selectedTag }}}`)
 }

I ran into a problem when I changed the rich text editor from default to Ckeditor.
When the user focuses on text and selects a custom variable, Canvas is showing {{variable}} and existing content, but in fact it's in reversed (correct) order: existing content and {{variable}}. See the screenshots:
Before:

Selecting the variable:

Result:

But model saves the correct content:

versions:
grapesjs: 0.21.4
grapesjs-mjml: 1.0.5
grapesjs-plugin-ckeditor: 1.0.1

Config for Ckeditor:

 {
          onToolbar(el) {
            el.style.minWidth = '350px'
          },
          options: {
            colorButton_enableMore: true,
            colorButton_colors: 'ffd106,fff,000',
            startupFocus: true,
            extraAllowedContent: '*(*);*{*}', // Allows any class and any inline style
            allowedContent: true, // Disable auto-formatting, class removing, etc.
            enterMode: 2, // CKEDITOR.ENTER_BR,
            extraPlugins:
              'sharedspace,justify,colorbutton,panelbutton,font,colordialog',
            toolbar: [
              { name: 'styles', items: ['Font', 'FontSize'] },
              ['Bold', 'Italic', 'Underline', 'Strike'],
              { name: 'paragraph', items: ['NumberedList', 'BulletedList'] },
              { name: 'links', items: ['Link', 'Unlink'] },
              { name: 'colors', items: ['TextColor', 'BGColor'] },
              ['JustifyLeft', 'JustifyCenter', 'JustifyRight'],
            ],
          },
        }
