Firefox cannot be moved by dragging the CSD title bar

[dimkr]

This happens with JWM 2.3.7 or 2.4.0 and any recent version of Firefox, when MOZ_GTK_TITLEBAR_DECORATION=client, browser.tabs.drawInTitlebar=true and browser.tabs.inTitlebar=true (the title bar checkbox is unchecked).

JWM properly hides the window title and the outline, but the block that starts at

jwm/src/event.c

Line 427 in 6099a92

if(np) {

seems to have no effect when dragging.

As far as I see, Firefox uses _NET_WM_MOVERESIZE, but HandleNetWMMoveResize() doesn't get called because JWM ignores the window.
