Fences renders markup around non-accessible items.

Issue

Most Fences templates render out field items with a foreach loop and call render() over each item. The render call is wrapped in some HTML for the respective element, For example, field--fences-strong.tpl.php.
The issue arises when the item may not be visible in its current scope, I.E. $item['#access'] = FALSE;. The render function obeys this and does not render the item, however fences still wraps the item which leads to dirty markup.

Proposed Solution

When fences will contribute a template suggestion to a rendering field (in hook_preprocess_field), it should also sanitize the items variable to ensure only visible items are passed to the template.
