Now that InkResponse has a focus node in it, the delete button has a separate semantics node, which causes it to appear in the examples/flutter_gallery/accessibility_test.dart search for nodes to measure, and it's coming up as too small: it's 18x18 instead of 48x48, since the tap target is only the delete icon itself.

Fixing this will probably require wrapping the delete icon in a larger gesture detector above the InkResponse.
