Causes undo widget not to work

[RedHatter]

When auto.fu is enable the undo widget stops working. If I type 'thing' and hit undo the 'n' disappears (should be the 'g'), if I hit it again nothing happens.

Hi, @RedHatter. Thank you for your report.

Ugh… undo does not play nice somehow, but I cannot find any workarounds for now. Sorry for the inconvenience.

Perhaps, auto-fu.zsh performs lots of destructive operations (such as modifying parameters ($BUFFER and such), calling other widget and so on) without considering these destructivenesses which break other widgets like undo you mentioned.
