The new behavior is as follows:
IF a user has a token and `features` is not set, we treat it as if the
feature was enabled.
IF a user has a token and `features` is set, we check if the feature
name has a value of "true".
`isJwtFeatureEnabled` also provides a way to specify the default value
in case there is no token.
The active speaker list in redux is alpha sorted, we need to ensure dominant speaker is at the top otherwise it can get truncated based on the available number of visible slots in the filmstrip.
