After I complete 20 reviews on a single day for some review queue, I typically see a message similar to this example (for the First Posts):
Thank you for reviewing 20 first posts today; come back in 6 hours to continue reviewing.
However, after the recent changes to the Review page, the images of the 6 most recent reviewers of that review queue will look like in this sample:
Note how, in the above image, for the "first posts" review queue, the 6 profile pictures seem to be squeezed to the right: their entire width is like about the width of 5 profile pictures for any of the other review queues where I didn't complete 20 reviews yet.
This happens to me on an iOS device (running 9.3.5), and this in about 5 different SE sites and/or review queues over the past few days. No idea so far how it looks like in the most recent iOS version.
How nice, merci beaucoup!!!, I refuse to believe that this is the new way to say "merci for all those reviews today", is it? ... I hope this is rather an undocumented feature, aka bug.
PS: Looking at the same review page around the same time on a Win PC (using any of the common browsers) seems to work fine, no matter which width I use for my browser window.
