Description

[Max Uetrecht]

Attachment: Tab_reopened.jpg

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.13; rv:64.0) Gecko/20100101 Firefox/64.0

Steps to reproduce:

1. Open any pdf file (e.g. http://www.pdf995.com/samples/pdf.pdf) 
2. Open tab overview
3. Switch back to the tab, where you opened the pdf


Actual results:

After switching back, the PDF file is no longer loaded. I have to reload the page in order to view it again (see screenshot)

I am using Firefox 14.0 Build 12646 on my iPhone X with iOS 12.0 Build 16A366


Expected results:

The PDF should be kept loaded, when switching between tabs.
