I think this was fixed by <https://webkit.org/b/168446>.
Wrong screenshot.
Created attachment 302538 [details] 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!
