[bug]: unhandled ZLE widget: history-substring-search/autosuggest-accept

[DarioDarko]

Describe the bug

after replacing zsh-syntax-highlighting with fast-syntax-highlighting i get these errors:

zsh-syntax-highlighting: unhandled ZLE widget 'history-substring-search-up'
zsh-syntax-highlighting: unhandled ZLE widget 'autosuggest-accept'
zsh-syntax-highlighting: unhandled ZLE widget 'history-substring-search-down'

i kept the recommended load order

syntax-highlighting -> autosuggestions -> history-substring-search

the only other zsh plugin i use is fzf-tab, which i load at the very beginning

despite those errors i cant identify any actual issue, accepting autosuggestions and history-substring-search both work as expected. for now ive appended 2> /dev/null to my source command, because i think those error messages are just false positives

Steps to reproduce

• source zsh plugins in the load order mentioned above
• add read after sourcing fast-syntax-highlighting to see the errors

Expected behavior

no error messages
