When the _ENABLE_LEGACY_CONTROLLER_SUPPORT flag is disabled, the
controller
local isundefined
. This causes the controller created by{{render}}
to have an undefinedtarget
(so it swallows any actions triggered).This properly sets the
target
torouter:main
if there is noparentController
present.Fixes #13182.
