MI breakpoint events not emitted when breakpoint is modified using CLI

Hi, 

I just noticed that -breakpoint-created / -breakpoint-modified / 
-breakpoint-deleted events are not emitted if I create them using CLI
interpreter. 

Following Pedro's suggestion [1], I start GDB with CLI interpreter
and then spawn a (secondary) MI interpreter using "new-ui mi <some
pty>" cli command. Then if I create a breakpoint using "break
some_func" using CLI interpreter (running on "primary" TTY), I get
no events on MI tty. If enter CLI command on MI TTY, I do get them. 

Is it a bug or a feature? If feature, what's the rationale behind? 

Thanks! 

Jan
