Blocks in the content region are given the wrong width if there are more one present.

If I assign more than one block to the content region in a fusion_core subtheme, they get the wrong width classes assigned to them. The width assigned to each block, where there are x blocks present, is 1/x * width of the content region, which is calculated correctly. So if I have 2 blocks in the region, they each take up half the width of the region; 3 blocks, one third; 4 blocks, a quarter, etc.

It seems to be this snippet from template.php, within fusion_core_preprocess_block() causing the problem:

  if (strpos($classes, $grid['name']) === false && $assign_grid_units) {
    // Stack blocks vertically in sidebars by setting to full sidebar width
    if ($vars['block']->region == 'sidebar_first') {
      $width = $grid['fixed'] ? $grid['sidebar_first_width'] : $grid['width'];  // Sidebar width or 100% (if fluid)
    }
    elseif ($vars['block']->region == 'sidebar_second') {
      $width = $grid['fixed'] ? $grid['sidebar_second_width'] : $grid['width'];  // Sidebar width or 100% (if fluid)
    }
    else {
      // Default block width = region width divided by total blocks, adding any extra width to last block
      $region_width = ($grid['fixed']) ? $grid['regions'][$vars['block']->region]['width'] : $grid['width'];  // fluid grid regions = 100%
      $width_adjust = (($region_count == $total_blocks) && ($region_width % $total_blocks)) ? $region_width % $total_blocks : 0;
      $width = ($total_blocks) ? floor($region_width / $total_blocks) + $width_adjust : 0;
    }
    $vars['classes_array'][] = $grid['name'] . $width;
  }

Maybe we need another condition for $vars['block']->region == 'content'?
