 Hi @johnbillion.

 Twenty Seventeen doesn't have any custom page templates. The issue
 involves deleting a custom page template, so it can't be reproduced with a
 theme doesn't have any.

 Our site is www.stanford.edu. I really can't switch themes on that site
 anyway, and our custom theme requires that certain plugins be enabled. I
 wrote the custom theme, and I know it does not interact with Preview in
 any way. It's mostly just defining custom post types and providing a few
 custom endpoints. However, one of our required plugins, licensed from a
 third party, does have it's own "Live Preview" functionality built in
 React. I will reach out to the vendor and see if they can find any
 interaction between their preview functionality and WP core's. It's hard
 to imagine, tho, that their functionality would trigger a write to the DB.
 But it's certainly possible, and I'll work with them to try to narrow down
 the interaction, if any.

 I know what a colossal job to test a zillion bug reports from a zillion
 random users running in customized environments, and of course you need us
 in the community to do due diligence to narrow down the issue to WP core.
 And I will try to do so. But if you're aware of any other issues re custom
 page templates and / or live preview, maybe you could add this issue to
 the testbed for those issues?

 Thanks for your thoughtful attention.

 -JB
