Dragover issue in Meteor - drag-and-drop

Question

I've just started learning Meteor (and Templating). I really enjoy it so far. However, I'm running into a weird issue using HTML5 native drag n drop events on a table. Note that I'm not using jQuery events.
I have a table with droppable td and draggable elements.
So my table template looks like this:
<template name="table">
<table>
{{#each row}}
<tr>
{{#each col}}
<td>
{{#each elements}}
{{>element}}
{{/each}}
</td>
{{/each}}
</tr>
{{/each}}
</table>
</template>
Template.tasktable.events({
'dragover td': function(evt) {
evt.preventDefault();
},
'drop td': function(evt) {
evt.preventDefault();
var id = evt.dataTransfer.getData('Text');
Collection.update({_id: id}, {$set: {value: this.value}});
}
});
Then my element template looks like this:
<template name="element">
<div draggable="true">{{value}}</div>
</template>
Template.element.events({
'dragstart': function(evt, tmpl) {
evt.dataTransfer.setData('Text', this._id);
}
});
For some reason that is melting my brain, the drag over event is being followed by a rendering event, as you can see on the dev tool image here: http://cl.ly/image/3O1S2d1j1f1a
This is extremely painful as dragover is being fired a lot and subsequently the dropevent is queued after several seconds. I have no idea where that comes from, it looks like domutils.js is being called.
Hope I'm clear enough.
Thanks so much.
EDIT
I managed to prevent the rendering event to appear, by removing the dragover event from the Template events and adding
$(document).on('dragover', 'td', function(evt) {evt.preventDefault();})
which is jQuery but doesn't get caught by domutils.js or listeners.js from Meteor.

Based on #Cuberto answer in the comments, I've successfully managed to solve the problem by upgrading Meteor with their new upcoming templating engine Blaze UI (which is still work in progress and not released yet).
Blaze UI uses jQuery events, and this seems to fix restyling layout issues mentioned above.
Should you want to permanently upgrade to Blaze UI, you need to run from the terminal:
meteor update --release template-engine-preview-10.1
Should you want to keep using the old templating engine that comes with the current release of Meteor (0.7.0.1), the fix I mentioned in the EDIT of my original post solves it:
$(document).on('dragover', 'td', function(evt) {evt.preventDefault();})
