Min height converter throw error when new style is added to mobile breakpoint

[syno-jde]

Hello!

I want to have the possibility to define specific margin and padding in desktop and mobile like min-height but it's throw an error in the back-office.

Step to reproduce

1. Add mobile breakpoint to existing margins_and_padding field (Vendor/PageBuilder/view/adminhtml/ui_component/pagebuilder_base_form.xml):

<?xml version="1.0" encoding="UTF-8"?>
<form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">
    <fieldset name="advanced">
        <field name="margins_and_padding" formElement="input">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="default" xsi:type="null" />
                    <item name="breakpoints" xsi:type="array">
                        <item name="mobile" xsi:type="boolean">true</item>
                    </item>
                </item>
            </argument>
        </field>
    </fieldset>
</form>

2. Add padding or margin in mobile view in Banner block form. Save. Error is throwed in the console.
