This Code Renders the Correct Display

Note the use of the space between shortcode brackets. (curley brackets used instead of regular to prevent the shortcode from being processed):

Fenced:
{posts-by-tag tags = "fenced" number = "3" excerpt = "false" thumbnail = "false" order_by = "title" order = "asc" author = "false"} {/posts-by-tag}
Bathroom or Port-a-Potty:
{posts-by-tag tags = "bathrooms" number = "3" excerpt = "false" thumbnail = "false" order_by = "title" order = "asc" author = "false"} {/posts-by-tag}
Very Shady:
{posts-by-tag tags = "super shady" number = "3" excerpt = "false" thumbnail = "false" order_by = "title" order = "asc" author = "false"} {/posts-by-tag}

The output looks like this:

The ones that Break

Bathroom or Port-a-Potty:
{posts-by-tag tags = "bathrooms" number = "3" excerpt = "false" thumbnail = "false" order_by = "title" order = "asc" author = "false"}{/posts-by-tag}

Very Shady:
{posts-by-tag tags = "super shady" number = "3" excerpt = "false" thumbnail = "false" order_by = "title" order = "asc" author = "false"}{/posts-by-tag}
