Can't click through people

[Remixful]

Why can't I use the X key to click through people anymore?
I tried changing the x-ray hotkey to something else and the X key still doesn't work.

This is intentional but really anoying.

For change it, download the source code and at LivingLifePage.cpp in line 25434 edit:
mXKeyDown = false;
by:
mXKeyDown = true;
