It's modal, so it blocks the entire browser until the dialog is dismissed. That's terrible interaction design, except for actions that would melt your computer.

It's modal, so it blocks the entire browser until the dialog is dismissed. That's terrible interaction design, except for actions that would melt your computer. I understand that the library focus is on visualization and not on realistic and usable examples; I put the blame on browser implementors - they should have fixed that problem years ago, instead of relying on developers to do the right thing. Edit - Update: I've tried it on Firefox and it does the right thing, blocking only the current tab; blocking the whole application must be a Chrome-only thing.
