Not so in WebKit. Of course, our implementation of addRange() already deviates from Firefox original a lot, because we don't support disjoint selections. 60776 1 17155 ap 2007-11-09 07:26:38 -0800 Created attachment 17155 test case 60779 2 ap 2007-11-09 08:02:55 -0800 If this is fixed, then it will make sense to implement Selection.removeRange(), which unbreaks the link. 109303 3 ap 2009-02-11 08:19:40 -0800 *** Bug 23885 has been marked as a duplicate of this bug. *** 109395 4 eric 2009-02-11 16:42:04 -0800 Ok, I've investigated Gecko's Selection more closely. Attaching a test case in a minute. FF's getRangeAt(x) functions on live range objects (as we knew already). When addRange(range) is called, a range is appended to the range list. The range list is kept sorted first by document order of the start positions, then by length of the ranges. The focus and anchor are set to the start/end of the last range added. If the last range added would be sorted to somewhere other than the end of the list, it still becomes the new focus/anchor. If that range is later removed, then the last sorted range in the range list becomes the new focus/anchor. I think we want to design our own API. This one seems kinda screwy to me. 109396 5 27579 eric 2009-02-11 16:47:14 -0800 Created attachment 27579 JS for test case (ignore the PASS/FAIL values) which shows FF's screwy behavior note that the PASS/FAIL values for this test do not correspond to any browser or desired behavior. I have just been using this to test what FF/WebKit do, and planned to update it to match the desired behavior if we chose to match FF's Selection API, which I don't think we really should do. 1325063 6 tkent 2017-07-03 01:48:45 -0700 Chromium fixed this. 1527719 7 db 2019-04-16 06:05:07 -0700 This is probably a duplicate of https://bugs.webkit.org/show_bug.cgi?id=145212, right?
