Simple array scroller skips items with value 0

Hi I have a simple array that is a long list of numbers. They all start by default at zero. But the scroller don't render any item with value zero. As soon I put any other number they appear.

Code example that works:
``
` `
`

'data() { return { headers: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] } }'

Code example that does not work:
(template is exactly the same)

'data() { return { headers: [0, 0, 0, 0, 0, 0, 0, 0, 0, 0] } }'
