Follow up to I340b9e7e91960713c0ebb4d3d26e2ae2d5628f37 The layout styles reference internal CSS classes within Vector components that may change at any time. For legacy layout, I leave the styles the same (they have a FIXME) As Aron noted on code review the impact such a change could have on user styles. For modern however I simplify the styles as follows: * The top margin on the form is promoted to the main element - this has the same end result. * Likewise the width dimensions are moved from child elements to the parent Bug: T249363 Change-Id: If923a5dddaac6217462e75d476e07d923ee1743f
