Comment:

 @haykuro yes, looking at the logic, this can definitely happen.
 I have not dug too much into possibilities because I'm currently triaging
 tickets, but I wonder if this can be happening on a healthy WP or if this
 is caused by a faulty code brought by a plugin or something like that.
 But can you explain the exact conditions for this to happen, ideally step
 by step
 If you can reproduce this in [https://wordpress.org/playground/ WordPress
 Playground] it would be better.
