To reproduce this bug, navigate to the URL, then triple-click the word “four”. Then Shift-click in the word “two”, then Shift-click in the word “one”. The selection extends to the words “five” and “six”, but it shouldn’t.

I can reproduce this with r233395 in macOS High Sierra 10.13.6.
Comment 3 mitz 2018-07-12 19:44:48 PDT 
It also reproduces with built-in Safari in that version of macOS, so it’s not a particularly recent regression.
Comment 4 mitz 2018-07-12 19:55:00 PDT 
I was able to reproduce this all the way back to r226018
Comment 5 Wenson Hsieh 2018-07-12 20:15:24 PDT 
Oddly, I'm unable to reproduce this on 10.13.4 (I tried both system Safari and STP 60).
Comment 6 mitz 2018-07-12 20:21:14 PDT 
This comes down to the behavior of VisibleSelection::expandUsingGranularity, which makes it at least somewhat related to bug 164519.

I wonder if there’s some extra global setting or preference that affects this (something like “smart copy and paste”).
