Collapse-O-Matic issues on iPhone, browser's window not resizing

Seems we’re experiencing some issues on Safari iPhone. Tested on several devices. The collapse function is ok, but the browser window do not resize updating the scroll, so any content below the opening size of the window remains truncated.

Any help? ?? Tks in advance.
