Feature Request: CF doesn't include a 'clear field' button in compendium search

[esheyw]

In most systems this is just a feature gap, but in PF2e it's a regression, since the system search includes it. I'd love to get one of these: in the CF search field. Copying the core implementation is probably(?) simplest, but if you have any ideas for improvements re: foundryvtt/foundryvtt#9086, that'd also be neat.
