Should we just add valueInSingleWindow into the error message here so its easier to see what went wrong?

In this case, I'm adding the input element, which is what should be meaningful to the user

nit: to avoid confusion, can we make this message more generic? Looking at the validation code, it can fail for reasons other than message size (e.g. attribute key/value size too large)
