Gas Grenade is not affected by less/reduced detonation time modifiers

Gas Grenade detonation time does not change when socketed with Expedite.

The tooltip changes but the in game behaviour does not. Detonation time is visibly the same.

To a lesser extent, gas grenade also seems unaffected by Volatile Grenades keystone (25% reduced detonation time for grenades), although this one is a bit less obvious than Expedite gem.

Just bumping as this is still bugged.

However I noticed something extra:

Wierdly, if you socket a gem that increases the detonation time of the grenade first (like long fuse) THEN WITH THAT gem TOGETHER, if you then socket EXPEDITE all of a sudden it starts working as expected.

Super wierd bug, but it's definitely there.

True, tree node and supp gem doesnt work.

I have assumption it cant go lower then 2 seconds for some reason, reduction is working but hard capped at 2s.

Bumping this old thread because it still seems to be the case in 0.3. Gas grenades fuse duration is completely aesthetic if you try to lower it at all.

GGG ? NEED AN ANSWER PLEASE
