Is it possible to open helm minibuffer while hydra is open ?

[pcompassion]

I first open hydra with foreign-keys run
Then I run helm-M-x.

Something is mesed up, the window is there but hydra is gone.
How to make the two coexist or at least properly disable hydra?

I find if I run helm-M-x first then hydra, it works fine.
But not the other way around.

I tried setting up
:on-enter (add-hook 'helm-minibuffer-set-up-hook 'hydra-disable)
