Hi,
Thank you for the details, it helps a lot!
I think this might be only a temporary cache issue, as it seems to be working fine on my end: https://i.imgur.com/dwFYg8p.png
I tried to replicate it with multiple random keywords, clicking in and out, refreshing, new search, but it works on both browsers.
There is an error in the console, but that is not related to the plugin, although it would be better if it was corrected, to make sure it does not affect it in any ways. Try clearing the browser cache, site cache and CDN to make sure it is not caused by them. Let me know!
