Currently theControllerTrait::render andControllerTrait::renderView methods assume that when thetemplating service is available it can always render the given view via that service.

However, that might not be the case. For example ifframework.templating is not configured to support thetwig engine for example but only some other custom engine, e.g.

framework:templating:engines:       -foobar

it will fail when the given view references a Twig template for instance and the configured engine cannot render that.

TheSymfony\Component\Templating\EngineInterface whichtemplating implements defines asupport method:

which should be used here, in order to make sure thattemplating actually does support rendering the given view.
