Yes, the sync from web to UI process was supposed to be implemented in bug 182868 but the patch is no longer working with the new approach. All test cases involving programmatic scrolling are known to fail right now. Fixed via bug 195099. *** This bug has been marked as a duplicate of bug 195099 *** |
