The in-line help (Ctrl + Shift + Space) don't display - on the pop-up - the value of a constant defined by including another constant.

Exemple :
------------
<?php

define('FOO', 'bar');
echo FOO;

define('BAR', FOO . 'bar');
echo BAR;
?>
------------
If I show the inline help (Ctrl + Shift + Space) on the FOO, the pop-up show "FOO = bar" .

If I show the inline help (Ctrl + Shift + Space) on the BAR, the pop-up show "BAR = ?" .
As if the software doesn't resolve the use of a constant on a define !

I try both on the 7.2 and the 7.3 beta version, some behaviour.
