Bug reports:

When rendering svg, if position: absolute; is used on the svg element, and it is not located in the upper left corner of the parent container (left: 0; top: 0;), when it is converted into an image through SVGElementContainer, it will generate Incomplete rendering. The reason is: XMLSerializer will calculate the position attributes of the element, resulting in incomplete converted images.

中文原文 (English is not good, hope to understand)

在渲染svg时, 如果svg元素上使用了 position: absolute; 定位, 并且没有位于父容器的左上角(left: 0; top: 0;), 在通过 SVGElementContainer 转化为图片时, 会产生渲染内容残缺。原因是: XMLSerializer 会将元素的定制属性计算进去, 导致转化的图片出现残缺.
