Bug - Normal Heal block bug vs Valentine

[Joegm]

On recent days everytime i fight against any prestige or marqueed Val with Lovecrafted they keep regaining hp even with the heal block already active.
Is this a real bug?
Or heal block only applyes against regular regen?

I'll have my team look into it. If you have an example of where you're seeing it consistently that could help, especially if you have video of it happening.
