custom element set before a custom elements but displayed after

[bruno darrigues]

Hi the community,

i set section with two elements :

<date-histo bar-data={{aggregations}}></date-histo>

<hot-table  id="HOT" datarows="{{contents}}">

but after rendering, the hot-table is displayed before the date-histo.

An important information, the date-histo is a d3 custom element and 

...
<template>
   <svg id="barchart" data={{barData}} width="{{ width }}" height="{{ height }}"></svg>
</template>
...

and the d3 selctor is this.elem = this.$.barchart;

i think i do something wrong but i don t understand.

Thx for your help

Best regards
Bruno
