Steps to reproduce the issue

Anywhere in your template/module options make a new field

<field 
	name="testrange" 
	type="range" 
	label="Test Range" 
	description="Test range desc" 
	min="-10" 
	max="10"
	step="0.1" 
	class="" 
	default="0"
/>

Check module/template admin form

Expected result

Expecting the form play nice with 0 (zero) values and default values.

Actual result

System information (as much as possible)

Joomla 3.9.6
php 7.3.4
mysqlnd 5.0.12-dev

Additional comments

Possibly related to #8928, I tested the number field with same settings, all good. Going to settle there for now.
