Steps to reproduce the issue

• I'm using subform for my module parameters
• I have this code on my xml :

<field name="items" type="subform" formsource="modules/mod_modulex/fields/item.xml" min="1" max="4" multiple="true" layout="joomla.form.field.subform.repeatable-table" groupByFieldset="true" label="Subform Field" description="Subform Field Description" />

• This is the content of the item.xml

<?xml version="1.0" encoding="UTF-8"?>
<form>
<fieldset name="items_fieldset" label="Fields">
    <field
        name="type"
        type="list"
        default="0"
        label="Type"
        description="Enter Type"
    >
        <option value="0">Small</option>
        <option value="1">Medium</option>
        <option value="2">Large</option>
    </field>

        <field name="for_large"
            type="text"
            label="Additional entry for large" showon="type:2" />
</fieldset>
</form>

Expected result

The field for_large is hidden until I choose 'Large' in the field type

Actual result

The field for_large is hidden for the first item only. When I add the second item and so on, the field is always showing up. See this gif cast attached below

System information (as much as possible)

Joomla 3.6.2
