[css3-exclusions] Few questions regarding text-indent and shapes bounding box

Hi All,

We have some doubts regarding text-indent and shape's bounding box when the
shape exceeds the containing block size.

1) When an exclusion content or shape content has text-indent css property
using percentages, how the percentage value should be resovled ?
Whether we need to use line-width of the bounding box or the line-width of
the shape?

2) If an exclusion box has a shape defined using shape-outside, and the
shape is bigger than the bounding box (ex: shape-outside: circle(50%, 50%,
80%)), the content should wrap around the bounding box or the shape?
