Find method not working properly - A possible bug in simple_html_dom library for PHP

simple_html_dom library for PHP features a strange behavior in version 1.5. I think this is a bug.

You add dynamic object with class .a2 to an existing object .a1, by modifying its innertext property.

You call find() method to search for .a2 objects, like this:

The problem is probably that updates using innertext are not getting converted to proper HTML DOM nodes.

The workaround is to save HTML DOM object to string, after setting innertext value, and then to load it back again from string to a new HTML DOM object.

Sample code:
