OutputTransformFn is not used when setting an empty value

[angheladrian]

When a OutputTransformFn function is configured, this is not always called when the control value is set programmatically.

Is this a regression?

Works fine with version 8.0.2

I would say it was introduced with the fix for #1447

Description

🔬 Minimal Reproduction

Consider having an input:

<input type="text" formControlName="amount" mask="separator.0">

When setting the values in code:

form.amount.setValue(null)

Then the OutputTransformFn is not called.

I think the problem is in NgxMaskService.formControlResult method.
Correct would be: this.onChange(this.outputTransformFn(''));
