In an Nwiki page, if you have a paragraph directly before a header, the edit link will be directly at the end of the header, instead of being aligned to the right

Reproduction steps

1. Create a wiki
2. Create the first page as Nwiki
3. In your text editor, insert the following:

   = A heading that works =

   A paragraph

   = A heading that will break =

   Another paragraph

   The second header's edit button will appear right next to it instead of on the right. Clicking on it will give the following error:

   The requested URL /integration_master/mod/wiki/edit was not found on this server
