dynamically rerendered row breaking hflex min column

Steps to Reproduce

run zkfiddle
https://zkfiddle.org/sample/1urqkpa/1-dynamically-rerendered-row-breaking-hflex-min-column

click button in sequence
A) -> B) ->A)

Current Result

the first column with hflex-min gets truncated

Expected Result

the first column with hflex-min has the same width as when rendered initially (with visible container)

Debug Information

it seems rerendering the a row while the whole grid is invisible results in incorrect min width calculation

Workaround

zkfiddle contains a commented out workaround to call fireSized on the container and contents whenever it becomes visible

    <div id="container" visible="true">
      <!-- workaround -->
      <attribute w:name="setVisible"><![CDATA[
        function() {
          this.$setVisible.apply(this, arguments);
          if (this.isVisible()) {
            zUtl.fireSized(this, true);
          }
        }
      ]]></attribute>
      ...
