mdSelect: width is incorrect with layout-column and flex

[mckenzielong]

mdSelect sets an incorrect min-width when flex and layout column are set on the md-select-menu-container div. See this codepen for an example. On the first click, the md-content will also have an incorrect min-width, but will be correctly set on subsequent clicks.

Additionally, shrinking the width of the window size while the select menu is open, and then scaling back up will cause the min-width set on the md-content to become incorrect.

Probably related to this calculation: minWidth = targetRect.width + centeredRect.paddingLeft + centeredRect.paddingRight;. It also seems like calculateMenuPositions should actually update the min-width set on the md-content node?

 if (shouldOpenAroundTarget) {
        contentNode.style['min-width'] = targetRect.width + 'px';
 }
//shouldOpenAroundTarget = false.
