Infinite growing height on content areas for on-page editing due to CSS transitions

* {
  transition: all 0.3s linear;​
}

The fix is easy though, I just had to override these rules with the following:

[data-epi-property-name] {
  transition: none;
}

Understandably a CSS rule on * is a bad idea, but width or height transition rule on DIV makes a reasonable amount of sense. 
I figured this might be helpful to others encountering similar problems.
