monitors are not supposed to change the TS. You can think at monitors being 'const' methods of the TS. Also, TSMonitor is called at the beginning of each step , see here https://gitlab.com/petsc/petsc/-/blob/master/src/ts/interface/ts.c#L4169

does not seem to stop the iteration in a user monitor function. I have verified that it works from a post step method. Is this intentional?
