Can't use prefixed tokens returned from node_token in node context

Using the latest panels I attempted to add a custom content pane, that rendered %node:created:raw, however, I kept getting a blank value.

This is my first time adventuring into anything related to ctools/tokens, but the problem seems related to the fact that ctools_context_entity_convert() calls token_info() to get a list of all valid tokens like so:

  $tokens = token_info();

  if (isset($tokens['tokens'][$token][$type])) {
    $values = token_generate($token, array($type => $type), array($token => $context->data));
    if (isset($values[$type])) {
      return $values[$type];
    }
  }

However, token_info() only triggers hook_token_info, which in the case of nodes only returns the root tokens such as 'changed' and 'created', but not the nested date tokens for each such as 'changed:raw'. The nested date tokens are returned by calling hook_tokens(), which isn't called until token_generate().

So, due to the if condition, the function early outs thinking that there is no token 'created:raw'.

For now, I (perhaps naively) commented out the conditional:

  if (isset($tokens['tokens'][$token][$type])) {

Which allows it to reach token_generate(), which allows the 'created:raw' token to be added by hook_token.

Does anyone have ideas on a proper patch for this?
