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. 1441547 1 webkit-bug-importer 2018-07-12 10:07:30 -0700 <rdar://problem/42125941> 1441769 2 mitz 2018-07-12 19:34:14 -0700 I can reproduce this with r233395 in macOS High Sierra 10.13.6. 1441771 3 mitz 2018-07-12 19:44:48 -0700 It also reproduces with built-in Safari in that version of macOS, so it’s not a particularly recent regression. 1441774 4 mitz 2018-07-12 19:55:00 -0700 I was able to reproduce this all the way back to r226018 1441782 5 wenson_hsieh 2018-07-12 20:15:24 -0700 Oddly, I'm unable to reproduce this on 10.13.4 (I tried both system Safari and STP 60). 1441783 6 mitz 2018-07-12 20:21:14 -0700 This comes down to the behavior of VisibleSelection::expandUsingGranularity, which makes it at least somewhat related to bug 164519. 1441785 7 mitz 2018-07-12 20:24:19 -0700 I wonder if there’s some extra global setting or preference that affects this (something like “smart copy and paste”).
