[Core] Multiple floating elements without ID causes segfault

[sammonius]

If there's more than one floating element being drawn without an explicit ID, the program crashes with a segmentation fault. I'm not sure if this is because floating elements don't have automatic ID's or for another reason.

(If this can't be fixed, it should at least be documented)

        // causes crash
        CLAY(CLAY_LAYOUT({.sizing = {CLAY_SIZING_GROW(), CLAY_SIZING_GROW()}})){
			CLAY(CLAY_FLOATING({}), CLAY_RECTANGLE({ .color = {255,255,255,255} })){ CLAY(){} }
			CLAY(CLAY_FLOATING({}), CLAY_RECTANGLE({ .color = {255,255,255,255} })){ CLAY(){} }
        }

        // doesn't cause crash
        CLAY(CLAY_LAYOUT({.sizing = {CLAY_SIZING_GROW(), CLAY_SIZING_GROW()}})){
			CLAY(CLAY_ID(("A"), CLAY_FLOATING({}), CLAY_RECTANGLE({ .color = {255,255,255,255} })){ CLAY(){} }
			CLAY(CLAY_ID(("B"), CLAY_FLOATING({}), CLAY_RECTANGLE({ .color = {255,255,255,255} })){ CLAY(){} }
        }

I've also tested it with IDI's and it doesn't crash if the indicies are different. I haven't tested what would happen if one has an ID and one doesn't, though.

Thanks for raising this one, definitely sounds like a bug so I'll get it fixed up for you 🙂
