Reviewed by Antti Koivisto.

When ellipsis is present
1. we don't shrink the truncated text box (or the root inline box)
2. Hit testing beyond the ellipsis usually means out of the block hit test.

However intrusive floats can float right at the edge of the ellipsis content and yet still be inside the block container. In such cases we can't use the regular text box/root box geometry and need to take truncation into account so that we don't see the truncated text/root inline box as an overlapping content (this is similar to legacy line layout).
