This is due to WRONG syntax on javascript, but Firefox and Chrome they will fix the javascript syntax and will not throw any error. The attatchement can test this problem, on Firefox/Chrome the result rectangle is in Green, but use webkit to render it, the color will be Red. 1525020 1 coldnew.tw 2019-04-06 06:50:20 -0700 This issue may duplicate with #173537, but #173537 can't reproduce this issue. 1672804 2 coldnew.tw 2020-07-18 09:00:00 -0700 This problem is found on webkitgtk 24 or below version, and fixed on webkitgtk (or the same version in Safari) 26.
