小提琴：https://jsfiddle.net/gjy1t16p/6/

如果您在Chrome中查看此内容并将窗口拖动到980px以下,它将按照我上面描述的方式工作.然而,在Safari中,虽然我没有设法完全重新创建问题,但是盒子垂直堆叠.

正如我所提到的,结果是不可预测的 – 当在我的网站上实现时,布局实际上比我制作的小提琴更接近工作.在网站上,2 x 2布局有效,但前提是第四个框内没有文本/小部件.一旦它包含到达框的整个宽度的内容,它向下移动到第三个框的下面,就像我尝试在其后添加的任何其他框一样.

如果有人之前遇到过这个bug并知道如何解决它,我会非常感激.我整天都在努力解决这个问题,而且我完全没有想法.
