There's a stack of dialogs being created on top of each other without coordination

This can be seen in the image below, where a user-select dialog appears on top of the tutorial dialog:

This happens because we don't have a central coordination for those auto-appearing dialogs and because some of them (like the Tutorial one) spawn itself, overriding the behavior of it's "show" props.

We should better coordinate those so only one dialog appears at a given time and so that the order of those dialogs make sense.
