Using ng-repeat with md-table directives, i have columns rendering when running Chrome < 65.0 but disappearing when running Version 65.0.

table(ng-if="table.scenario.loadcaseIds.length > 0" md-table flex="grow" md-progress='promise').flexible-columns
      colgroup
        col(
          ng-repeat="loadcase in table.scenarioLoadcases"
          span=1
        )
      thead(md-head md-order='query.order' md-on-reorder='logOrder')
        tr(md-row)
          th(
            md-column
            ng-class="{active: loadcase.id === table.highlightedLoadcaseId, selected: table.selectedLoadcaseIds.includes(loadcase.id), invalid: table.invalidLoadcaseIds.includes(loadcase.id)}"
            ng-repeat="loadcase in table.scenarioLoadcases"
            ng-mouseenter="table.hoverLoadcase(loadcase.id, true)"
            ng-mouseleave="table.hoverLoadcase(loadcase.id, false)"
          ).loadcase
            span(
              ng-click="table.editLoadcase(loadcase)"
            ).md-icon-button {{loadcase.name}}
              md-tooltip(ng-if="!table.disabled" md-direction="top") Edit Loadcase
            md-button(
              ng-click="table.toggleSelectedLoadcase(loadcase.id)"
            ).md-button.md-icon-button
              md-icon.visibility.small visibility
              md-tooltip(md-direction="right") Toggle Loadcase
            md-button(

            ng-if="!table.disabled"
            ng-hide="table.scenario.homogenization_state"
