No automatic scrolling into the right after adding a new tag #85

Hi,

I've configured Tags with horizontalScroll: true and TagsTextField enabled.

After having added four tags (Test1, Test2, Test3, Test4), I no longer see the TagsTextField to enter my fifth tag (Test5). I need to manually scroll into the right.

I would expect the widget to automatically scroll into the right, every time a new tag gets added, to ensure TagsTextField is always aligned to the right.

Thanks.

Best Regards.
