iterated variable in for..in loops no longer highlighted #4521
Description
Until a couple months or so ago, if you had something like:
for (final element in listOfStuff) {....}
when the cursor is on element, all instances of that in the loop are highlighted, as vscode normally highlights variables. But recently it has stopped. If the cursor is on listOfStuff, the highlighting still works as expected, but nothing is highlighted when it's on element. See screenshot:
What used to happen (and I think what is supposed to still happen?) is that element should be highlighted, including where the cursor currently is, along with the two places it's used inside the loop. But you can see that's not happening.
Additionally, if you do put the cursor on one of them inside the loop, both instances inside the loop are highlighted (as expected) but the one in the 'for-in' line still is not highlighted.
I don't know if this is even a dart code extensions problem, or something with vscode itself, or something where a default setting was changed that I need to change in settings json, but no amount of googling has helped. I have depended on this code highlighting a ton previously so this change is really throwing me off.
