Currently whenever you open a PDF in the browser with the default PDF viewer it opens with (I'm assuming) 100% zoom level. Zooming in to the pdf until it almost fits the width of the page works. However, this zoom level is reset as soon as I navigate to another tab and come back and I have to zoom it back again. This can get quite annoying especially if you're navigating between multiple tabs all with PDF documents.
As far as I can tell Safari maintains the zoom level of the PDF no matter which tab or how many times I switch. I'd like for the Orion browser to replicate that behaviour. I understand that there is the alternative of the PDF.js viewer but I prefer the minimal PDF viewer that MacOS presents by default.
