morph preserves input value on active element

[MichaelWest22]

Description

When we morph inputs values that have changed there default value we also push an update to the inputs internal value property to respect the server request to update the values input. But if the input is active and focused with the user editing it right now we can block this value update to preserve the end users active input text they may have just changed. This allows you to morph an active form with the last input change events data returned from the server without losing any text changed during the time it takes for the request to complete.
