Summary	0001188: Setting a root makes branch length strange
Description	I was preparing a slide for my lecture, so I wrote a tree file in the newick standard format by usual text editor. I saved it and opened it by the newest MEGA X (10.0.5). To make the tree smart, I tried several times to put the root of the tree. Then the branch length leading to the outgroup (in my case orangutan) got longer and longer.
Steps To Reproduce	(1) Prepare a slingle-line file that contains a tree in the newick tree format as follows: (orang:10,(human:4.5,chimp:4.5):0.5,gorilla:5); (2) Double click the file. (3) Set a root on the longest branch several times.
