Looks weird, probably using margin-left.
I think this was fixed by <https://webkit.org/b/168446>.

Timeline Tab (RTL)
Things to be fixed, probably in smaller bugs:
- DataGrid resizers resize the wrong column
- DataGrid borders are broken on some columns
- Timeline overviews should draw RTL
- Timeline rulers are backwards too
- Disclosure triangles are messed up
- Need to investigate localization of px, px^2, ms, etc.
- List of timelines is on wrong side of overview
- Similar issues for Memory, Allocations, and Rendering Frames
Feel free to make smaller bugs!
