I'm trying to make my Inventory Control Tweaks (repo) mod work alongside itemscroller.

itemscroller causes malilib's MixinMouse#hookOnMouseClick(...) to cancel mouse clicks, so my mixin that makes it so certain items shift-click to the player's offhand isn't reached.

I've created an itemscroller-compat branch where I tried registering a click handler using

InputEventHandler.getInputManager().registerMouseInputHandler(new ClickHandler());

however my handler is reached after the stack has already moved (the same way it does in vanilla), so clickedStack is always empty when I reach this line.

I'd appreciate help fixing compatibility between the two mods.
