Tagify Input Adds Unexpected \r\n Causing Incorrect isDirty State in react-hook-form in setting's mix mode.

[jktilavat]

When using react-hook-form with Tagify input Component, the value returned from the input includes an unexpected trailing \r\n, which causes react-hook-form’s isDirty to evaluate to true even when there are no meaningful changes to the form data. This affects form submission behaviour, especially the submit button’s disabled state.

Scenario

• Using react-hook-form's Controller to manage form state
• Using Tagify-based input component
• Relying on isDirty to control the disabled state of the submit button

❗ Problem

• The value returned from Tagify includes an extra \r\n even when it's visually empty or when tags are added.
• This causes react-hook-form to detect the form as dirty (isDirty = true), even though the actual content hasn't changed meaningfully.
• Attempting to strip \r\n via string manipulation resolves the isDirty issue, but introduces caret position issues — typing in the input causes the cursor to jump to the beginning of the field.

✅ Expected Behaviour

• The input value should not append an extra \r\n.
• When cleared, it should return "" or match the initial value.
• Manual workarounds (like .replace(/\r\n$/, '')) should not cause caret/cursor issues.

Are you talking about tagify in mix-mode?

Yes, this issue is occurring in mix-mode.

This won't be fixed.. sorry. I do not have the time capacity for this
