Paralysis + Battletide = Lose Dex AC (Even with Uncanny Dodge)

[Good Character]

Description of Bug Experienced:
This is more specific given I cannot find another testable, accessible scenario that would put me at the whims of a paralysis or condition that would flat-foot me that also applies Battletide penalities.

When paralyzed (i.e. via Hold Person) and then subject to Battletide penalities (i.e. enemy casted Battletide), you will lose all your DEX AC regardless if you have Uncanny Dodge I.

Steps to reproduce the Bug:
1. Be paralyzed
2. Have the Battletide aura envelope you
3. Have Uncanny Dodge I

Expected Result:
Maintain your Dexterity AC despite being flat-footed from the paralysis.

Actual Result:
Lose your Dexterity AC.

You can regain the Dexterity AC by leaving the aura of Battletide.
