Loading zdharma-continuum/fast-syntax-highlighting plugin via antigen breaks fig completions in zsh

Checks

[X] I have searched github.com/withfig/fig/issues and there are no duplicates of my issue
[X] I have run fig doctor in the affected terminal session
[X] I have run fig restart and replicated the issue again

Operating system

macOS 13.4.1 (22F770820d)

Expected behaviour

Fig completions work, regardless of the zsh plugins installed

Actual behaviour

Fig completions fail to appear if zdharma-continuum/fast-syntax-highlighting plugin is loaded in the .zshrc with antigen:

antigen bundle zdharma-continuum/fast-syntax-highlighting

Completions continue to fail even if this antigen bundle is commented out and shell is restarted. Completions also do not appear after running fig doctor, but did resume finally on fig restart

Steps to reproduce

Yes, as above, use antigen to enable the plugin in the .zshrc to reproduce this behavior.

antigen bundle zdharma-continuum/fast-syntax-highlighting
