[Bug]: Pink Hydra:exit does not call Hydra.layer.exit

[levouh]

Heads within a pink Hydra that have { exit = true } seem to work just fine, but when explicitly calling Hydra:exit() the hint is closed but the keys are not unmapped. In order to get this to work, I have to do something like:

local h = Hydra({...})

...

h.layer:exit()
h:exit()

when I believe I should not have to explicitly call exit on the layer itself.
