Possible perf gain.

Load feeds one at a time, and render what we can as the feeds are done.

If we go from the top to the bottom of the layout, and render until we hit something that's not ready, we can very likely render the above the fold caontent faster.

In my reference machine testing I saw improvements:

cached:
control:7.85/patch:6.61
no cached:
control:7.66/patch:7.3

To test, turn DS on and off, and watch it load.

If you watch it closely, you can see it loading from top to bottom as feeds are ready.

I have verified this issue with the latest Firefox Nightly (68.0a1 Build ID - 20190509214305) installed, on Windows 10 x64, Arch Linux and Mac 10.14.4. Now, the page is loaded from top to bottom as feeds are ready.
