Compatibility with Post Navigator

Hi, this plugin is great.

I found a small conflict though.

When using Admin Post Navigation https://wordpress.org/plugins/post-navigator/ …

When you add text content to a Admin Help Box in popup form the prev / next links automatically appear in the text of the admin help box popup.

In short this can be quick fixed via css by adding…

.wpbizplugins-cahb-content #post-navigator-prev,
.wpbizplugins-cahb-content #post-navigator-next {
  display: none;
}

I post the same on the authors support as well.
