Fix scroll into view not working when revealing method

This fixes a bug where the method row would not scroll into view when
revealing a method. The problem was that the `DataGridRow` component
on which the `ref` was set is a `display: contents` element, which
does not have a visual representation in the DOM. Therefore, it wasn't
possible to scroll the method row into view. This fixes it by moving
the ref to the `DataGridCell` component of the first column, which is
a normal element.
