Found this does not work either - no indentation or italic text
... am I doing something wrong?

<p style="padding-left: 50px;padding-right: 50px;font-style: italic;">' . trim($matches[1]) . '</p>

Using these did not work either <center> and <i>

BUT found <sup style="vertical-align: super;"sup>ABCsup</sup> worked
While <span style="vertical-align: super;">ABC</span> did not work.

For text-align in h1 tags use a p tag instead.
Not ideal as that breaks the link to style Header 1.

Any news about this issue, the alignment is not applied on all the heading!
