[prefer-self-closing-tags] closes ng-container with  

[twittwer]

Description and reproduction of the issue

The self-closing tag rule considers an ng-content with a non-breakable space as an empty tag.
But this is not true, as a non-breakable space is a rendered element.
The auto-fixer removes the non-breakable space, which causes a UI change.

{
  "rules": {
    "@angular-eslint/template/prefer-self-closing-tags": ["error"]
  }
}

<!-- input -->
<ng-container i18n>prefix</ng-container>
<ng-container>&nbsp;</ng-container>
<ng-container i18n>suffix</ng-container>

Rendered: prefix suffix

<!-- auto fixed output -->
<ng-container i18n>prefix</ng-container>
<ng-container />
<ng-container i18n>suffix</ng-container>

Rendered: prefixsuffix
