Issue with cache macro rendering an inline macro

if you have the following content with the testinline macro sending back some simple text

This is {{testinline /}}

This is {{cache}}{{testinline /}}{{/cache}}

On the first load, both lines will be the same with the text flowing normally in the same paragraph.
However when reloading and the cache macro operating, then the content from the cache macro will move to it's own paragraph.
