ZF-11316: Zend_Dojo_Form_Element_Editor minHeight can be set only to em

Description

Currently the minHeight property of the Zend_Dojo_Form_Element_Editor can only be set to em, whereas the height property can be set to em, px or %.

It would be nice to be able to set the minHeight with em, px or %.

Comments

A patch which enables setting the minHeight as em, px or %. Leaving em as default, even if the default for the height property is px, to make it BC.

Tests for this issue.

Patches look good; applied to trunk and 1.11 release branch.
