> visually consistent In Chrome on Windows it shows a back-and-forth bouncing progressbar that is not at all similar to the system's indeterminate progress bar styling. I've never seen this used elsewhere, other than here in this Chromium implementation of <progress>. It's (mostly*) not objectionable but it definitely doesn't blend in. * Suffers from a newbie trap: if you're going to bounce back and forth, you need to make sure there's a frame where the bouncer is all the way at the end of the control before the direction switches. This implementation doesn't, so sometimes the moment when it hits the edge of the progressbar happens between frames, so you miss the actual bump which looks disconcerting.
