On mobile (can't check main, but I suspect this bug isn't there on main), on a tag search page, the number next to the featured tab seems to be behaving strangely.
The excel tag has 4 featured (bountied) questions.
When I sort by frequent the featured tab(dropdown) has a "(409)" next to it.
When I sort by newest it is 22
When I sort by featured, it is 11.
None of these are the actual number, 5.
