• I agree to follow the Code of Conduct.
• I have searched for existing issues that already report this problem, without success.

Ionic Framework Version

v8.x

Current Behavior

Starting from v8.6.0, ion-input is not parsing {} and [] correctly.
Typing {} gives [object Object] and [] returns no string as the output.

Expected Behavior

Expectation is that ion-input will allow to enter arrays such as [], and [abc].
It should also allow JSONs such as {}, and {test: true}.

Steps to Reproduce

This behavior is supported in v8.5.9 and started breaking in v8.6.0
