p tags added

Hi Dave, when I edit a Content Block, sometimes the <p> tag is added to the block.

For example, if the content of a block is another block like [contentblock id=other]. If it is opened on the Visual tab, when I move to the Text tab I see <p>[contentblock id=other]</p>

If I reload the page (without making any change), the block is loaded on the Text tab, and the tags are not added. So, it is a bug when the block is loaded on the Visual tab.
