Moment's isDST method has a warning in the documentation:

NOTE: This function is a HACK. moment has no way of knowing if a given time is in actual DST or not. Some time changes in a zone are DST related, some are not, and without complete timezone information it can't know.

Moment currently checks the winter and summer time, and if the offset matches the summer offset (and summer off is different than winter off), then it reports DST. This works in vast majority of cases, but as mentioned above, is not "correct" and won't work for all cases.

Because eastern Kazakhstan had a one-off change of time zone, the naive guessing in Moment is being tripped up and thinks it's a DST shift. Although it's unfortunate, it's not something we're likely to fix, given the maintenance-only status of the project.
