[Affected versions]:
- latest Nightly 52.0a1
- latest Aurora 51.0a2

[Affected platforms]:
- Windows 10 x64
- Windows 7 x64
- Ubuntu 16.04 LTS x64
- macOS 10.12 (Sierra)

[Steps to reproduce]:
1. Launch Firefox.
2. Go to http://hpr.dogphilosophy.net/test/.
3. Play the FLAC audio sample. (last audio format in the menu).
4. Wait until the audio is at 1:36 seconds. (or fast forward to the final section of the audio file)

[Expected result]:
- The FLAC audio progress bar is properly playing to it's end.

[Actual result]:
- The progress bar is skipping 2 seconds from 1:36 to 1:38. (it jumps to the final of the FLAC file)

[Regression range]:
- This is not a regression, as it is reproducible since the feature (FLAC support) landed in Firefox (Nightly 51.0a1 from 08-23-2016).

[Additional notes]:
- with other audio formats like ".opus", ".mp3", ".wav" the issue is no longer reproducible

I would mark this as invalid. With many flac file; the duration is actually estimated. That it doesn't fully match what was determined at the start is not surprising.

Additionally; the progress bar isn't always refreshed when it needs to be refreshed. It's a UI issue
