Steps to reproduce
Create 2 files in dynalist with separate content.
Open each in a separate tab in the web browser
Document contents should be distinct.
At first documents are distinct, but after some time editing each document, document 2 is mix of it’s original content, and unrelated content from document 1.
I can scroll up past the start of document 2 and start to see document 1.
Windows 10, Chrome browser.
