Interderminate progress bars still not working (Chrome and Firefox)

[elken]

This is about Bulma.

Overview of the problem

This is about the Bulma CSS framework

My browser is: Chrome 78 and Firefox 71

Description

Duplicate of #2258 and #2352 I know, but it's still not resolved for me on implementation.

The docs work fine (as an aside I'm also using Bulmaswatch but the docs for that show fine too), but copying the line onto my application shows a solid empty bar on firefox and a solid filled bar on chrome.

If I remove the progress class it animates as normal just with no styling.

Steps to Reproduce

1. Drop <progress class="progress is-medium is-dark" max="100">45%</progress> into application (no other css overriding it, no js frameworks at all)

Expected behavior

Animated as in either bulma docs or bulmaswatch docs

Actual behavior

Chrome and Firefox
