Toxic Growth damage not improved by Concentrated Effect gem.

Toxic Growth pustule explosion damage does not seem to be improved by the Concentrated Effect support gem.

The Toxic Growth explosion radius does get reduced but the explosion damage stays the same instead of being improved by 40%.

Please look into this issue.
Thank you.

Will require further testing but I noticed the explosion damage is not shown in the tooltip, only the damage when the arrows land is, which is not considered area damage and thus is unaffected by Concentrated Effect. That might be why the increase in damage is not reflected in the tooltip. If that is the case, adding the explosion damage to the tooltip would make this interaction less confusing.
