Will move to header in commit. > I'd add a test for what happens when the playbackRate is 0. Currently, bad things happen when setting the playback rate to 0. We will deal with that correctly when we implement pausing and the introduce the concept of the hold time. I'm just about to start on that, see webkit.org/b/178932. But we can add a test for getting the current time with playback rate = 0, this already works, and should always report currentTime = 0. Will add another test in the commit. 1366024 4 graouts 2017-10-30 08:09:12 -0700 Committed r224181: <https://trac.webkit.org/changeset/224181> 1366363 5 webkit-bug-importer 2017-10-31 06:41:06 -0700
