[Rendering] Bug Title Here Min Max for Input.Date not working on Teams Desktop

Target Platforms

Other

SDK Version

desktop Teams version 25094.310.3616.953

Application Name

Microsoft Teams

Problem Description

Adaptive Card Input.Date fields with min and max constraints are not consistently enforced across Microsoft Teams. In Teams Desktop, the min/max values are either ignored or can be overridden via manual input. In Teams Mobile (Android/iOS), they work as expected.

Start with the provided Adaptive Card JSON and reproduce the Input.Date behavior in Teams Desktop, comparing it with the stated Android and iOS behavior. Done means the min and max values are consistently enforced in the desktop renderer, including when a date is entered manually.
