Changed Freemarker macros optionalAttributes and renderAttr in brick-utils

The Freemarker macros optionalAttributes and renderAttr in @coremedia/brick-utils did remove attributes with empty values. This has been changed to support empty values. If you need to hide empy attributes, set the value to cm.UNDEFINED . These macros are used for example by the macros optionalLink and optionalTag .

Examples:

<@utils.optionalLink href=link attr={"class":"example", "download": "", "hideAttribute": cm.UNDEFINED}>Example</@utils.optionalLink>

Result:
<a href="link" class="example" download="">Example</a>

Changed bricks media and mediaelement

The bricks "media" and "mediaelement" used the scss macro stretch-absolute() for the CSS selectors .cm-media--responsive and .cm-mediaelementwrapper iframe . This is only working, if the outer box set an aspect-ratio-box() , which is not part of the bricks. So we moved usage of stretch-absolute() to the example-bricks and example-themes.

Upgrade steps:

If you rely on our responsive image concept, please check your themes and bricks for aspect-ratio-box() usages and add stretch-absolute() for the inner box elements. Alternatively readd the removed CSS defintion to your theme:

.#{$cm-media-prefix} {
  &--responsive {
    stretch-absolute();
  }
}

.cm-mediaelementwrapper {
  > iframe {
    @include stretch-absolute();
  }
}
