InvPane 사용시 다른 슬롯 오버랩

[myoun]

다음 코드에서 오류가 납니다.
영역이 겹쳐서 나는 오류인데, https://github.com/monun/invfx/blob/master/invfx-core/src/main/kotlin/io/github/monun/invfx/internal/frame/InvFrameImpl.kt#L83 에서 y+width가 맞는지 의문이 듭니다.

        val invFrame = frame(5, Component.text("강화").color(NamedTextColor.YELLOW)) {
            // result pane
            pane(0,0, 9, 1) {
                val ent = itemWithMeta(ItemStack(Material.ENCHANTING_TABLE)) {
                    displayName(Component.text(""))
                }
                for (i in 0 until 9) {
                    if (i != 4) {
                        item(i, 0, ent)
                    }
                }

                onClick { x, y, event ->  println("$x, $y")}
            }

            pane(0, 1, 9, 1) {
                val gp = itemWithMeta(ItemStack(Material.YELLOW_STAINED_GLASS_PANE)) {
                    displayName(Component.text(""))
                }
                for (i in 0 until 9) {
                    item(i, 0, gp)
                }
            }
        }
