Two-finger scrolling not working on mail messages in OS X Catalina 10.15.6 but works on other apps

Two-finger scrolling not working reliably on mail messages in OS X Catalina 10.15.6 but works on other apps. I have MacBook Pro 2018. Problem has persisted for a year or more. I've force-quit Mail, rebooted OS X many times. 1-finger and 3-finger gestures work fine. 2-finger scroll does not, almost half the time. This only happens with Mac Mail app.

Interesting. It sounds like the emails are being created/sent in a particular way which somehow bamboozles the Mail program. It could be a deficiency in Mail; it could be that the mail sender is breaking some rules. Maybe someone with knowledge of the inner workings of mail can chime in here. I've never encountered such a problem with any mail I have ever received.
