Advance width using smart components

[FlorianPircher]

Is this the same issue as here:?

Missing advance width in smart component

This is expected, as components attach just like they would using mark attachment (and thus not contribute to the advance width of the base glyph). Use #entry and #exit anchors instead: (Also, using the “entry” and “exit” names instead of a generic “connect” allows you to chain components. For example, add both an #entry and #exit anchor to _smart.n-second-stroke and now you can create an m from a stem and two consecutive acres.)
