Mismatch value Between UI and Form Model in NumericTextBox When Pasting Decimals

  When using NumericTextBox in a reactive form with format: 'n0' (integer) and validateDecimalOnType: true, pasting a decimal value like 1.1 results in the input rejecting it visually, but the underlying FormControl still retains the invalid value (1.1). This leads to inconsistencies between the UI and form model.

Simple Sample:https://stackblitz.com/edit/angular-78kfto1r-vmrejap4?file=src%2Fapp.component.html,src%2Fapp.component.ts

Replication Procedure:

  • Run the sample
  • Paste an invalid decimal (e.g., 1.1) into the input.
  • You can see the console

Expected Output:The form control should reset to the last valid value or be cleared, matching the input field.

Current Output:  Input reverts visually, but form control still holds 1.1.
