Timeline 4.17.0 layout with margin.item.horizontal = 0 is broken

In previous versions setting the margin to zero worked like this

Now in 4.17.0 it seems to be broken:

My options are as follows: var options = { start: Date.now() - 60 * 60 * 1000, end: new Date(Date.now() + 8 * 60 * 60 * 1000), editable: true, margin: { item: { horizontal: 0 } } };

Here is an example of the data used: [{"id":1080,"group":2027,"content":"13 (Crips-A)","start":"2016-11-15T13:01:33","end":"2016-11-15T18:11:55.43","setupSeconds":1800,"materialNumber":"Crips-A","targetQuantity":4000.00,"actualQuantity":4000.00,"orderNumber":"13","orderStatus":"Finished"},{"id":1094,"group":2027,"content":"27 (Flakes)","start":"2016-11-15T18:11:56","end":"2016-11-15T23:36:19.551","setupSeconds":1800,"materialNumber":"Flakes","targetQuantity":4200.00,"actualQuantity":0.0,"orderNumber":"27","orderStatus":"Planned"},{"id":1100,"group":2027,"content":"33 (Flakes)","start":"2016-11-15T23:36:20","end":"2016-11-16T05:00:43.551","setupSeconds":1800,"materialNumber":"Flakes","targetQuantity":4200.00,"actualQuantity":3990.00,"orderNumber":"33","orderStatus":"Running"},{"id":1102,"group":2027,"content":"35 (Choc1)","start":"2016-11-16T05:00:44","end":"2016-11-16T10:32:08.112","setupSeconds":1800,"materialNumber":"Choc1","targetQuantity":4300.00,"actualQuantity":0.0,"orderNumber":"35","orderStatus":"Planned"},{"id":1105,"group":2027,"content":"38 (Whitey7c)","start":"2016-11-16T10:32:09","end":"2016-11-16T15:07:28.626","setupSeconds":1800,"materialNumber":"Whitey7c","targetQuantity":3500.00,"actualQuantity":0.0,"orderNumber":"38","orderStatus":"Planned"},{"id":1107,"group":2027,"content":"40 (Flakes)","start":"2016-11-16T15:07:29","end":"2016-11-16T19:35:48.065","setupSeconds":1800,"materialNumber":"Flakes","targetQuantity":3400.00,"actualQuantity":3400.00,"orderNumber":"40","orderStatus":"Finished"}]
