Created attachment 97343 [details] work in progress It turned out that when moving across p's (-2.html tests), we can't use lineTop for x coordinate for the reasons explained in my patch for the bug 55481.

Created attachment 97344 [details] work in progress (with tests) Oops, forgot to add tests.

Created attachment 97520 [details] fixes the bug

This bug is about fixing modify('move', 'forward'/'backward', 'line'), not about arrow keys navigations. That's tracked by the bug 62833 and blocked by this bug. The code change itself is pretty trivial; the patch is big because I've added many tests and renamed some functions.

Comment on attachment 97520 [details] fixes the bug It would make this patch easier to read if the renaming was done in a separate preparation step. The part of this code I am not sure about is absoluteLineDirectionPointToLocalPointInBlock.

Thanks for a review! (In reply to comment #5) > (From update of attachment 97520 [details]) > It would make this patch easier to read if the renaming was done in a separate preparation step. The part of this code I am not sure about is absoluteLineDirectionPointToLocalPointInBlock. Yeah, I don't like that function either. I rewrote it a couple of times to get it feel right but it's still ugly :( I'm more than happy to do some refactoring in follow up patches.

Of course, these tests require platform-specific results so I'll stick around on #webkit and rebaseline as needed.
