Right side tile border doesn't match left side

It seems that the z-index or something may be off. As you can see in the screenshot, the left-box and arrow pointing towards the timeline act as "one", while the right-side still has a border covering part of the arrow.

Yep you're right. Looks like a CSS artifact, not sure when it came in. Should be easy to fix i'll get to it soon thanks for finding it.

Sweet. I'll take a look in a bit too and may push a PR. Cheers
