@justinbmeyer thank you for the feedback. well, for the moment I don't think so. for me, I know that this is a workaround.
The main idea for the issue is that, according to the documentation, it shouldn't have this behaviour. therefore it's a bug, isn't it?
I discovered this issue just fooling around with canjs and unconsciously include
can/view/modifiers. Therefore it's an issue that is not obvious how it occurs and I think I'm not the only one facing it.
Also can you please indicate if there is another place but
Control.setup to replace
