State diagram: Misalignment of entry points with concurrent substates

[jmewes]

Observed

After adding a concurrent state, the placement of the entry points is not at the state boundary anymore.

Expected

I tried to create a diagram like this:

Steps to reproduce

@startuml

hide empty description

state foo {
  state qux <<entryPoint>>
  state quux <<entryPoint>>

  [*] --> zxc
  qux --> zxc
  quux --> spqr

  --

  state wombat
  state shme
}

As workaround, a pseudo state might be used for the region:

@startuml

hide empty description

state foo {

  state Region1 #line.dotted {
    state qux <<entryPoint>>
    state quux <<entryPoint>>

    [*] --> zxc
    qux --> zxc
    quux --> spqr
  }

  --

  state Region2 #line.dotted {
    state wombat
    state shme  
  }
}
