Product list Show summary on hover problem

Hi team! I haven’t updated my plugins or theme in a while.
I don’t plan to update anything right now, but I noticed that some things aren’t working correctly.
It only works poorly in Google Chrome.

Please watch the video and test the site.
I cleared the custom styles, but it still doesn’t work as expected or as it did before.
What’s the problem?

I think the issue is somewhere with JS loading or CSS compilation…

PS problem in “Show summary on hover”
