  Issue 719014: column-fill: balance of a vertical block in orthogonal context incorrectly rendered
  https://bugs.chromium.org/p/chromium/issues/detail?id=719014

  <meta content="" name="flags">
  <meta name="assert" content="This test checks if a multi-column container with 'column-fill' set to 'balance' will not break an unbreakable run of text and will honor min-content inline size of a block that has its writing mode set to 'vertical-rl'. In this test, the word 'TEXT' should not break, even if div#multi-col's 'height' is set to '49px'.">

  <style>
  div#multi-col
    {
      background-color: yellow; /* Not part of the test */
      columns: 2 auto;
      column-fill: balance; /* Balance content equally between columns, if possible. */
      height: 250px; /* more than enough to display "TEXT" */
    }

  div#unbreakable-block
    {
      background-color: lime; /* Not part of the test */
      font-size: 50px;
      line-height: 1.2; /* Not part of the test */
      writing-mode: vertical-rl;
    }
  </style>

  <p>Test passes if the word "TEXT" is unbroken and rotated 90 degrees clock-wise.

  <div id="multi-col">
    <div id="unbreakable-block">TEXT</div>
