Workflow for note-taking while reading PDF: can't open PDF-view and highlights-view next to each other

Hey,
I would like to take notes between my PDF highlights during reading.
The way that I thought this would be possible is to open the PDF-view and highlights-view of the same document next to each other. But that doesn’t work. Each time I change to the other view in one pane, the other pane changes its view too. Is this a bug or does someone know any reason for that?
Does someone know a good work around to achieve my goal?
My current work-around is to open a browser-remnote-window next to the remnote app, but this is not satisfying.

Feature is not there yet, you can go vote - View PDF and its Highlights side by side
