Description

Insert a progress element with the following syntax <paper-progress indeterminate class="blue" secondary-progress="80"></paper-progress>

Expected outcome

I expect that the secondary progress is always visible, independent of the foreground animation

Actual outcome

Every other cycle the foreground animation let the secondary progress bar disappear.

That's because we use another element (with the same background color as the container) to overlay the primary progress to create that animation. In other words, using secondary progress with indeterminate is not supported.
