Grid and Items render twice

[OMEN44]

Discovered this when using the on:change event, it appears that this event fires twice in quick succession (This is very clear if you print the timestamp).

Currently i'm using this work arround:

let lastTimeStamp = -1;
const onChangeHandler = (event) => {
	if (!(event.timeStamp - lastTimeStamp < 3)) {
		// handler code goes here
	}
}

This also appears to cause Svelte's #each template to trigger twice aswell, this can be seen simularly if you print to the console when the each template is renderd.
