Ladda spinner not showing when button also has ngDisabled

[MattDionis]

I have a button that looks like the below. When I remove the ng-disabled everything works fine, otherwise the spinner never appears.

<button
  ladda="vm.runningReport"
  data-style="zoom-in"
  class="btn btn-default"
  uib-tooltip="Run Report"
  tooltip-placement="top"
  ng-disabled="vm.parameters.length > 0 && !vm.parametersSupplied(vm.parameters.values)"
  ng-click="vm.run(query)">
  <i class="glyphicon glyphicon-play text-primary"></i>
</button>

@MattDionis I think this is complex issue. Can you show me demo page?

Here's a Plunker demonstrating a possibly related bug when using angular-ladda with Angular 1.6: https://plnkr.co/edit/dxQtXpnl3yaXPNE0KCB5?p=preview.

Update: looks like this is due to an intentional change to not remove boolean attributes when they are set to a blank string: angular/angular.js@3faf450.
