So, as a fix to this consider merging chromium patch: https://chromium.googlesource.com/chromium/src/+/f6dcdcf4917ba56f5576ef7d5d11d869630d2760 Test case from https://bugs.chromium.org/p/chromium/issues/detail?id=481985 > Open http://jsbin.com/zufeva/1/ > Start dragging on the first box (-webkit-user-select:none) and drag into the second (no -webkit-user-select). > IE and Firefox appear to implement their user-select variants differently where it controls whether selection can be STARTED. So there, if you start in the first box, you won't select text anywhere. 1626459 1 clopez 2020-03-05 19:29:57 -0800 (In reply to Carlos Alberto Lopez Perez from comment #0) > > So, as a fix to this consider merging chromium patch: > https://chromium.googlesource.com/chromium/src/+/ > f6dcdcf4917ba56f5576ef7d5d11d869630d2760 > This fix can't be merged as such. It causes issues on the web-inspector, the text on the console becomes non selectable. The same happened on chromium after merging it (it was reverted later).
