Confirmed, but my HTML-foo is not good enough to understand what is
wrong.

The HTML fragment in question is

<li class="off"><code>[&#xa0;]</code> foo</li>
<li class="off"><code>[&#xa0;]</code> <p>bar</p>

  <table border="2" cellspacing="0" cellpadding="6" rules="groups" 
frame="hsides">

The second item is _rendered_ with a newline when paragraph is inserted.

Probably, the reason is <p> tag in the first paragraph of the item.
I am not sure, however, if it is safe to drop it.

`org-html-paragraph' only drops <p> for first paragraph in an item that
is followed by either plain string or a sub-list:

((and (eq parent-type 'item)
           (not (org-export-get-previous-element paragraph info))
           (let ((followers (org-export-get-next-element paragraph info 2)))
             (and (not (cdr followers))
                  (memq (org-element-type (car followers)) '(nil plain-list)))))
      ;; First paragraph in an item has no tag if it is alone or
      ;; followed, at most, by a sub-list.
      contents)

ox-html: Better criterion for first paragraphs in lists

* lisp/ox-html.el (org-html-paragraph): Do not wrap first paragraph in
  an item within <p> tags in the most simple cases.

Thanks to Daniel Clemente for suggesting it.

The diff in the commit suggests that dropping <p> is not desirable when
non-paragraphs are present in the list. In the above example, a table is
present.
