ember-light-table: targetScrollOffset Error and scrollbar visible

I have a simple table in a template

{{#light-table table height='50vh' as |t|}}
  {{t.head
    onColumnClick=(action 'onColumnClick')
    iconAscending='fa fa-sort-asc'
    iconDescending='fa fa-sort-desc'
    fixed=true}}

  {{#t.body
    canSelect=false
    canExpand=true
    multiRowExpansion=false
    onScrolledToBottom=(action 'onScrolledToBottom')
    as |body|}}
    {{#body.expanded-row as |row|}}
      <div>
        {{#each foo as |msg|}}
          <p>{{msg.name}}: {{msg.value}}</p>
        {{/each}}
      </div>
    {{/body.expanded-row}}
  {{/t.body}}
{{/light-table}}

when I expand a row and the expanded content overflows the table height, the scrollbar appears and that’s ok. The problem is that when the expanded row is collapsed the scrollbar reamins visibile, and If I try to click on it a lot of errors are thrown in the console

Assertion Failed: You modified "targetScrollOffset" twice on 
<phoenix-client@component:lt-body::ember573> in a single render. 
It was rendered in "component:lt-scrollable" and modified in "component:ember-scrollbar". 
This was unreliable and slow in Ember 1.x and is no longer supported. 
See https://github.com/emberjs/ember.js/issues/13948 for more details.
