Not getting z foo<SPACE><TAB> completions

[rieje]

I'm not getting z foo<SPACE><TAB> completions and I'm not sure why. Latest versions Zsh 5.9, Zoxide 0.9.6.

My .zshrc is:
...
compinit
...
source /usr/share/fzf/completion.zsh
FZF_ALT_C_COMMAND= source /usr/share/fzf/key-bindings.zsh
...
eval "$(zoxide init zsh)"
alias z='__zoxide_z'

and I also removed zcompdump.

I run:

z /usr/bin
z ~/bin
z bin<SPACE><TAB>     <- here, I expect completions for both the paths have none

I'm on Arch and the path to the completions is already in fpath.

P.S. Unrelated, but anyone know of a tool similar to zoxide but doesn't record frequency? I would rather manually add a list of of entries and order by priority (this should make it more predictable). I could probably script something up but for a tool that's used as frequent as cd, I want to be sure it's the right solution and is efficient and complete with completions which I'm not sure how to write myself but can probably tweak from examples.

What is this line for?

alias z='__zoxide_z'

I had an alias z already, I was just using this to override my alias to test out zoxide.

I found the culrprit--I'm using fzf-tab-completion and commenting out sourcing its plugin works. I tried sourcing that plugin before and after eval "$(zoxide init zsh)" but could not get both to work. Are they simply incompatible?
