A bug of the HP-15C Collector's Edition running in HP-16C mode?

Thanks for reporting this.

It is known that the 15c CE's NOMAS 16C mode [f]+[BASE] display modes are not correct (the display should stay on as long as you hold down the [BASE] key) and this behavior you're reporting is really a side-effect of that core problem, but detailing it this way is useful to let folks know to not press another key so quickly and thus avoid having to reset. So, thanks!
