Environment

macOS 14.6.1 (23G93)

Angular version

Node version

Browser(s)

Chrome 131.0.6778.265 (Official Build) (arm64); Firefox 134.0 (aarch64)

Steps to reproduce the behavior

• Go to the stackblitz
• Type "United"
• Select the option United Kingdom, the control value displayed is { "name": "United Kingdom", "code": "GB" } which is the expected result
• Copy the input and paste it (in a more real-word usage, it would be the case of the user continuing to type and having his input perfectly matching the text of a suggestion). The control value displayed is "United Kingdom" and remains so even if on blur is triggered

Expected behavior

I would have expected the input to be transformed into an object whenever possible, not only on select
