WBR tag breaking hyperlinks

I just checked this on a test site. I added only this link to a post.

<a href="http://www.msrlm.org/mrlif/faqenglish.html" target="_blank">http://www.msrlm.org/mrlif/<wbr />faqenglish.html</a>

The result from the page source is:

<p><a href="http://www.msrlm.org/mrlif/faqenglish.html" target="_blank">http://www.msrlm.org/mrlif/<wbr />faqenglish.html</a></p>
  • Verify the site is using the latest WordPress version,
  • Temporarily disable all plugins to rule out a plugin conflict,
  • Switch themes to rule out a theme problem.
