Steps to reproduce the issue

Have multiple showon fields.

Eg.

<field name="sample_sw" type="radio" label="Sample Switch" default="1" 
	checked="checked" 
	class="btn-group">
<option value="0">JNO</option>
<option value="1">JYES</option>
</field>
<field name="sitetitle1"  type="text" default="" label="Sample Field" showon="sample_sw:1"/>
<field name="sitetitle2"  type="text" default="" label="Sample Field" showon="sample_sw:1"/>
<field name="sitetitle3"  type="text" default="" label="Sample Field" showon="sample_sw:1"/>
<field name="sitetitle4"  type="text" default="" label="Sample Field" showon="sample_sw:1"/>
<field name="sitetitle5"  type="text" default="" label="Sample Field" showon="sample_sw:0"/>
<field name="sitetitle6"  type="text" default="" label="Sample Field" showon="sample_sw:0"/>
<field name="sitetitle7"  type="text" default="" label="Sample Field" showon="sample_sw:0"/>
<field name="sitetitle8"  type="text" default="" label="Sample Field" showon="sample_sw:0"/>

Expected result

Possibly have the fields fade in/out after slideDown and before slideUp

Actual result

Additional comments

I have tried fixing this however ran in to trouble with certain variations (eg. the above XML where fields are both displayed and hidden with a switch).
