This is an improvement, fixing #372. It allows the use of indeterminate progress bars, as seen below:

You can do this by skipping the value attribute in your progress tag.

Proposed solution

It's an adaptation to @scottwernervt's code on the issue #372. Many other big frameworks support indeterminate progress bar styles, so why shouldn't Bulma? 😄

Testing Done

Tested on Chrome and Firefox on Linux, their latest versions. I consider it should work on the recent versions of any major browser, as this solution was proposed a year ago.
