Default Value is replaced by prefix

[chrisvidal]

I am using only the options `{"prefix": "https://" } to force an URL to be filled in.
But if the input already has a value, then the value is deleted by the prefix.
How to keep to the default value?

Same issue, if value of input is set for +48 123 456 789 cleave strips it to +48+48123456

My workaround: I set the default value after initialising the cleave component with Vanilla JS.

var config_key = document.getElementById('config_key');
var config_key_value = config_key.value;
var cleave_config_key = new Cleave('#config_key', {
	prefix: 'XXX-'
});
if (config_key_value) {
	config_key.value = config_key_value;
}
