about key bindings failing for CD **<tab>, but works for other bindings

[mirageglobe]

hi all, wonder if anyone can help? I have keybindings updated to "??" in my .bashrc, which is sourced by bash_profile. am using mac os x (monterey) via homebrew.

something weird that I couldnt figure out was vim ??<tab> works fine, so does ssh ??<tab> and export ??<tab>. however keybindings for CD ??<tab> and unset ??<tab> does nothing. ctrl+t works, ctrl+r works, so technically I can do cd <ctrl+t>. I am pondering about _fzf_comp_gen_dir() and maybe it has issues? I wonder if anyone has seen similar on latest fzf or has come across this? I have also changed the trigger to be ??? just in case, and still it doesnt work.

have spent quite some time.. disabling quite a bit of config and seems to be futile. it would be perhaps easier if it was not working at all and not partially :D, which doesnt make sense. would it be bash_completion@2 which maybe does something funky?

thanks for any hints or possibilities to look! 🙇
