Views render element #embed not working

Problem/Motivation

• Create a view with an "Embed" display.
• Attempt to render the embedded view using the following code:
  

  $variables['my_embedded_view'] = array(
    '#type' => 'view',
    '#name' => 'example_view',
    '#display_id' => 'embed_display',
    '#arguments' => array(),
  );
  

This leads to a fatal error: Unsupported operand types in core/modules/views/src/Element/View.php (line 63). This error is caused by ViewsExecutable::executeDisplay(), which returns NULL for Embed display plugins.

Now, the View render element already defines an #embed variable, which looks like it is supposed to render the view via preview() instead of execute().

So it looks like this should work:

$variables['my_embedded_view'] = array(
  '#type' => 'view',
  '#name' => 'example_view',
  '#display_id' => 'embed_display',
  '#arguments' => array(),
  '#embed' => TRUE,
);

Unfortunately, this does not work either, because the code which is supposed to detect whether #embed is not empty references embed instead.

The following works, but produces the following user error: "embed" is an invalid render array key.

$variables['my_embedded_view'] = array(
  '#type' => 'view',
  '#name' => 'example_view',
  '#display_id' => 'embed_display',
  '#arguments' => array(),
  'embed' => TRUE,
);

Proposed resolution

• Make the '#embed' variable work.
