Subject: [PATCH] Cover: Fix matrix alignment issue. (#28361)

For context, position absolute, combined with width/height 100% works in most cases, but is still subject to the box model, collapsing margins, and other hard-to-predict things. By replacing those with top/right/bottom/left values of zero, we set neither widths nor heights, but accomplish the same.
