Gibberish after navigating to an inactive tab in Firefox with encrypted content

I have many open tabs in Firefox, and some of them are unloaded. Sometimes, if I navigate to this tab, it displays garbage instead of decrypted content.

I have seen this many times, usually the "go back one page" button helps. I guess pastila encrypts the data twice when it happens
