I noticed an issue yesterday and it has to be to do with CSS styling.
I inserted an image (using TinyMCE toolbar) and left aligned it. It was the last thing on the topic.
When I hit submit I found that the small dotted footer line and freshness note just under it were going straight through the image. Since the image was left aligned I had a paragraph of text to the right of it that went half way. The there was this footer.
So it did not bypass this image and place the footer below the image. In the end I had no choice but to either leave the image with no alignment or center align it. Then the footer is correct.
Surely there should be a divaround the topic or reply content and then the footer and freshness note below that. It would then avoid this issue since the left aligned image would be inside that divand the footer area pushed down under the div.
