 The way previews are generated in WP 5.1 have changed from 4.x.
 IIRC, previously the page was saved to the database and a preview was read
 as HTML from there.

 Now previews feel slower and seem to be generated through another
 mechanism
 A number of errors are appearing in the new (?)generated(?) pages.
 1) Commented HTML is showing when it should be hidden.
 2) On my own site, some duplicate database results appear when they should
 be consolidated into one line.
 In my case, these are for events that ran across several days.

 Note: pages show as intended when page is saved and viewed normally.
 This issue with preview only appeared for me when I moved to WP 5.1
