Next to the "review" button at the top banner there is a number in an orange square that appears periodically. In the past it was a number indicating that there are suggested edits waiting to be reviewed, and pressing on it would take me to the suggested edit review.
Now it takes me to the general edit page, but more strangely is that it shows a number even though all the review ques are empty, and keeps it even after a refresh of the page.
What does the number mean?
On Stack Overflow, the number still works the same, shows how many suggested edits are waiting to be reviewed, and it takes me straight to the suggested edits review cue.
