This is a case I didn't think of until writing related tests, but I think it makes sense, because if there's any missing output and no inputs, that output will probably show up when the inputs do.
This is basically the same as test cbmi004 just for the case when all the inputs have multi-value wildcards so we do try to fire the callback, and we need to bail out at a later step when we collect all the outputs.

The first 4 of these tests (modified for the changed internals) pass when run against Dash v1.10 - so this clears the regression as far as I understand it. The other 5 tests all use wildcards so are not relevant to v1.10. cc @chriddyp @Marc-Andre-Rivet |

Wondering what would be required to be able to write this (and https://github.com/plotly/dash/pull/1212/files#diff-15692ba768eeab56e95aa409ab7c19b7R279) so that we don't use exceptions as flow control.

don't use exceptions as flow control
yeah I suppose that's cleaner now that they aren't always errors -> b44bd54

Is this meant to be console.error?
Fixes #1200 - regression in Dash 1.11 with callbacks that have outputs but no inputs.
