Cannot expand <iframe> height

[nil0x42]

I just created a render note, rendering an html code note based on iframe (to get original html display)

My html code note is like that:

<iframe style="min-height: 85vh; width:100%; height:100%;" src="data:text/html;charset=utf-8,%3C!DOCTYPE......" sandbox=""></iframe>

The dirty min-height: 85vh; is the only way i found to display the iframe with an acceptable height.

If i use min-height: 100%;, the iframe's height is only 154px, and i could not find why...
