[Bug 9224] It should be mentioned that setting playbackRate can be ignored. I.e. if playing backwards is not supported by the codec, if hardware acceleration does not support it, etc.

Ignoring may not be always the best response. It may be the case that the
underlying player may simply select the closest playback rate. In this case the
event ratechange indicates the closest value that was selected. For example,
player supports 2, 8, 16. A web application may try to use 3 in which case the
player selects 2 as the playback rate.

Knowledge of the available rates is also an issue.

Two issues should be resolved:
1. what happens when selecting a playback rate other than the available ones
2. what are the available playback rates

Note that (2) playback rates may change over time. Ads may not allow for
fastforward.
