handleSubmit not triggered for readOnly inputs when defaultValues are set

[mehrabFronto]

Description

When using react-hook-form with defaultValues and readOnly inputs (that are temporarily editable), handleSubmit does not trigger after changing the input value and re-disabling it.

It seems that the value in getValues() always returns the initial defaultValues and does not reflect the actual DOM value after editing, even though the input's value has visibly changed in the UI.

---

Reproduction Steps

1. Initialize the form with defaultValues.
2. Render an <input> with readOnly={true} and bind it with register().
3. On double-click, toggle readOnly to false to allow editing.
4. Change the value, then set readOnly back to true.
5. Call handleSubmit(onSubmit) after disabling the field.
6. The onSubmit callback is not triggered if the only change is in a readOnly field when defaultValues are set.

Expected Behavior

When the value of a readOnly input changes (while temporarily editable), react-hook-form should detect the change compared to defaultValues and trigger handleSubmit accordingly.

---

Actual Behavior

When defaultValues are set:

• getValues(name) returns the initial value from defaultValues.
• The change in the DOM is not detected.
• handleSubmit does not run or treats the field as unchanged.

If defaultValues are not set, everything works as expected.

Versions

• react-hook-form: 7.60.0
• React: 19.0.0
• Browser: Google Chrome
• OS: Windows 10

Additional Context

This issue seems related to how react-hook-form caches initial values from defaultValues and doesn't re-read the DOM value when the field is readOnly. It may require calling setValue() manually, but that should not be necessary if the field was temporarily editable.
