Content Moderation incompatible with Form Mode

If I add content moderation to an entity that has a form mode enabled, clear cache will show the following error:
Notice: Undefined index: type in Drupal\content_moderation\Routing\ContentModerationRouteSubscriber->setLatestRevisionFlag() (line 74 of core/modules/content_moderation/src/Routing/ContentModerationRouteSubscriber.php).

The function setLatestRevisionFlag() in Drupal\content_moderation\Routing\ContentModerationRouteSubscriber assumes that the default entity form will always have the entity type in$parameter['type'].
However the form mode of an entity has the entity type in $parameter['targetEntityType'] instead.

More specifically, if I replace

if ($parameter['type'] === 'entity:' . $entity_type && !isset($parameter['load_latest_revision'])) {
  $parameter['load_latest_revision'] = TRUE;
 }

with

if (isset($parameter['type']) && $parameter['type'] === 'entity:' . $entity_type && !isset($parameter['load_latest_revision'])) {
  $parameter['load_latest_revision'] = TRUE;
}
elseif (isset($parameter['targetEntityType']) && $parameter['targetEntityType'] === $entity_type) {
  $parameter['type'] = 'entity:' . $entity_type;
  $parameter['load_latest_revision'] = TRUE;
}

apparently all will work fine, but I'm not sure if this is a robust solution.
