Make image formatting consistent between Freeplane and Simply HTML component/editor

[cjwomack]

Hi there,

I have an issue with inserting images in HTML into main Freeplane mindmap.

I noticed that shtml looks like it doesn't support the style attribute in regards to css styling of height and width.

This isn't the main issue as the main issue is to do with Freeplane's display but maybe it would be good to have display behaviour consistent between the two or at least have a way to apply css re images in another component of the main Freeplane project

freeplane/freeplane#1852

Thank you
