Make clean-pinned-issues more visible - #3659

They look selected now, not a fan.

I don’t think I’ve seen that style anywhere else; if you have an example of GitHub using it we can discuss whether we should match it.

For example GitHub use this style for:

1. Emphasize some section in a view like notification actions banner and files list header.

2. To highlight items on a list like your own comments on issues and PRs and notifications on hover.

There are some guidelines about blue boxes in Primer docs https://primer.style/css/components/box#blue-box-theme

The selected/active style should be more like this:

Another suggestion 🤷‍♂️

Before	After

In my opinion, the 2px width seems more like a glitch than a feature 😶

Maybe this can go along with #3657, using the same colors? Do those colors work here?

That's a gray border, this is blue as per https://primer.style/css/components/box#blue-box-theme

@sindresorhus thoughts on the style? Worth the change?

I think they look too "heavy" now. Maybe we could reduce the background color opacity to half?

background-color: rgb(241 248 255 / 0.5);

I don't think this change is necessary after all. Thanks for opening the discussion though
