Thanks for your response, Brandon.
My blog URL is
https://hongjiho.com
My theme or plugins I use can be the problem,
but I suspect something that changed for Jetpack 5.0 causes this because:
– When I tested with Jetpack 4.9, the issue did not occur(I test with WordPress 4.8).
– A blog using Jetpack 5.0 (https://proinlab.com) shows the same issue.
– Another blog using Jetpack 4.8 (https://www.alphafactory.co.kr/) shows no issue.
– This happens on IE 11 and Chrome. MS Edge is fine.
To make my explanation clear, I captured screenshots.

Thanks again!
