(Whiteboard: [webcompat][geckoview:p3])

Probably needs a better title once the issue is fully figured out.
Adding [qf] for performance issue.


1. Navigate to: https://mamibuy.com.tw/talk/article/
2. Tap the Account icon (the muffin shillouette with a question mark) in the top right corner.
3. Tap the second tab.
4. Scroll the overlay contents to the bottom.
5. Scroll the background page.

**Expected Behavior:**
The scrolling is done smoothly, the  Login overlay is stationary.

**Actual Behavior:**
The Login overlay is stuttering when scrolling the background page.

**Notes:**
1. The issue is also reproducible on Firefox 56.0 Release (Mobile).
2. The issue is not reproducible on Chrome (Mobile) 61.0.3163.98.

https://perfht.ml/2xHI07J
Flags: webcompat?
Can be reproduced in Firefox 62.
Nothing to do with DOM.

I assume the profile is from Android. And devtools were open, since network-monitor.js takes some time.
And there is also some JS implemented ImageBlockingPolicy.js thingie.
and lots of jquery on the page.
