This joins fine, but its rare so early on I know the final layout, if you change the widths by using the circles to link them as a block to ease relocation of phrases like:
when you then do a join the text relocates and mangles
Even should you separate the blocks, the text mangles most of the time, it's rather frustrating..
I have previously reported this issue, about 2 years back, and has kinda hoping it may have been fixed by now..
