I noticed in 5.2 b5242, some formatting changes made in the editor (Example: Table Properties >> Width = 90%) will cause bad formatting changes in the print friendly page and vice-versa.
Even when resetting the page, it seems like you still need to go all the way back to the group tab and step your way back through each navigation tab before the page actually gets reset.
I have not tested any other themes, but it happens in the Madrid / Madrid theme.
Thanks
