wasm: make the "a11y enable" button cover window

Adjust the button geometry to match window geometry.
Screen readers may visualize the geometry, and this
makes it clearer that the button is relevant.

Setting the clip looks to be sufficient to keep the
button visually hidden, even if the canvas (which would
normally be ordered in front) is missing.
