Heatmap changes after zooming about leaflet.heat HOT 5 OPEN

I think this is because of this line https://github.com/Leaflet/Leaflet.heat/blob/gh-pages/src/HeatLayer.js#L141, leaflet heatmap will recalculate the heat value based on the zoom level which i think it is not the right behavior.

You can reproduce on the 10k example.

Zoom in here, 1 zoom at a time

It looks like this

Do a big zoom out/in fiddle around.

Ends up looking different, I got this (top middle has a big red bit):

I found that this bug is happening when the map zoom on different set of point.

For example if you zoom using the leaflet button you always get the same resultat with the heatmap.

But when you zoom at a different point you get different result. It seems that some point off the screen are not taken account for the gradient.
