Miscellaneous: Pet health in group window

[Mike]

As a cleric i have discovered an annoying little issue with the updating of party members pet health.
Under the red bar representing the groupmember health, there is a bit thinner green bar, representing the group members pet health.

If our group is engaged with a mob, and one of the group members pet is tanking, the health bar of the pet will not update accurate.

For instance, if the bar shows 50% health in the group window, when targeting the pet the real hp on the pet is only 30%.
Since i tend to group with two of my friends most of the time, who happens to have just pet classes, this is very annoying.

Anyone else experienced this?
Any ideas?
