In general we don't handle margins very well with selections (e.g. any page that puts all it's contents in a margin: auto container). Here's another case encountered in the real world. 1342002 1 jfernandez 2017-08-24 03:45:18 -0700 I don't think margins have a direct effect on the issue. I think that the root cause is extending the selection until reaching the float's container. I'll attach another case which I think reveals the same issue without margins. 1342003 2 318979 jfernandez 2017-08-24 03:45:56 -0700 Created attachment 318979 another test case 1342005 3 jfernandez 2017-08-24 03:56:56 -0700 FTR, the issue is clearly reproducible in current trunk. 1342006 4 jfernandez 2017-08-24 04:00:50 -0700 I can reproduce the issue described in both test cases in FF as well. 173321 2012-11-09 09:15:24 -0800 2012-11-09 09:15:24 -0800 reduced testcase scratch3.html text/html 953 ojan PHN0eWxlPgouY29sdW1ucyB7CiAgICBmbG9hdDogbGVmdDsKICAgIG1hcmdpbjogMjBweDsKICAg IGJvcmRlcjogMnB4IHNvbGlkOwp9Cjwvc3R5bGU+Cgo8ZGl2PlRoZSBjYXNlcyBiZWxvdyBzaG93 IGRpZmZlcmVudCBzaWRlIGVmZmVjdHMgb2YgdGhlIHNhbWUgYnVnLiBUaGUgc2VsZWN0aW9uIGFz IHlvdSBkcmFnIGZyb20gdGhlIGZpcnN0IGJveCB0byB0aGUgc2Vjb25kIHNob3VsZCBvbmx5IGlu Y2x1ZGUgdGhlIHRleHQgaW4gdGhvc2UgYm94ZXMgYW5kIHNob3VsZCBvbmx5IGluY2x1ZGVkIHRo ZSBhY3R1YWwgdGV4dCB5b3Ugc2VsZWN0ZWQuPC9kaXY+Cgo8ZGl2IGNsYXNzPSJjb2x1bW5zIj5T dGFydCBzZWxlY3Rpb24gaGVyZTwvZGl2Pgo8ZGl2IGNsYXNzPSJjb2x1bW5zIj5EcmFnIHRvd2Fy ZCB0aGlzIGFuZCBzdG9wIGluIGJldHdlZW4gdGhlIHR3byBibGFjayBib3hlcy4gV2UgZG8gYSBj cmF6eSBzZWxlY3Rpb24uPC9kaXY+Cgo8ZGl2IHN0eWxlPSJwb3NpdGlvbjogYWJzb2x1dGU7IHRv cDogMjAwcHg7Ij4KICAgIEJlZm9yZSBmbG9hdHMKICAgIDxkaXYgY2xhc3M9ImNvbHVtbnMiPlN0 YXJ0IHNlbGVjdGlvbiBoZXJlPC9kaXY+CiAgICA8ZGl2IGNsYXNzPSJjb2x1bW5zIj5EcmFnIHRv d2FyZCB0aGlzIGFuZCBzdG9wIGluIGJldHdlZW4gdGhlIHR3byBibGFjayBib3hlcy4gV2UgZG8g YSBjcmF6eSBzZWxlY3Rpb24uPC9kaXY+CiAgICBBZnRlciBmbG9hdHMKPC9kaXY+Cgo8ZGl2IHN0 eWxlPSJwb3NpdGlvbjogYWJzb2x1dGU7IHRvcDogNDAwcHg7Ij4KICAgIDxkaXYgY2xhc3M9ImNv bHVtbnMiPlN0YXJ0IHNlbGVjdGlvbiBoZXJlPC9kaXY+CiAgICA8ZGl2IGNsYXNzPSJjb2x1bW5z Ij5EcmFnIHRvd2FyZCB0aGlzIGFuZCBzdG9wIGluIGJldHdlZW4gdGhlIHR3byBibGFjayBib3hl cy4gV2UgZG8gYSBjcmF6eSBzZWxlY3Rpb24uPC9kaXY+CjwvZGl2Pgo= 318979 2017-08-24 03:45:56 -0700 2017-08-24 03:45:56 -0700 another test case dragSelectionExtent1.html text/html 273 jfernandez PGh0bWw+Cjxib2R5IHN0eWxlPSdmbG9hdDogbGVmdDsnPgpTdGFydCBzZWxlY3RpbmcgdGhpcyB0 ZXh0PGJyPgpmcm9tIGFueSBsaW5lLCBhbmQgZHJhZyB0aGU8YnI+CnNlbGVjdGlvbiBvdXRzaWRl IHRoZSB0ZXh0IGFyZWEuPGJyPgpOb3RpY2UgaG93LCBpbiBDaHJvbWUsIHRoZTxicj4Kc2VsZWN0 aW9uIGV4dGVudCAianVtcHMiIHRvPGJyPgp0aGUgdG9wIHdoZW4gdGhlIG1vdXNlIG1vdmVzPGJy PgpvdXRzaWRlIHRoZSB0ZXh0IGFyZWEuPGJyPgo8L2JvZHk+CjwvaHRtbD4K
