Metabox UI rough box shadow when in closed mode

[obiplabon]

Please check the following two images and compare side by side. I've added a red mark for your convenience. The drop shadow or box shadow doesn't look neat and clean.

Before

After

Changing the following css I've gotten better result.

.postbox .hndle, .stuffbox .hndle {
    border-bottom: 1px solid #eee;
    user-select: none;
}
// Changing the above styles to this
.postbox:not(.closed) .hndle, .stuffbox:not(.closed) .hndle {
    border-bottom: 1px solid #eee;
    user-select: none;
}

Thanks

Thank you @obiplabon for your ticket and welcome to Trac. Sorry for the long delay.

With the new Block editor, this issue is no longer happening. However, even on recent versions of WordPress, the report is confirmed with the Classic Editor plugin installed.

I'll mark this ticket as requiring design feedback so the Design team can share their thoughts on the matter.

Thanks @obiplabon for pointing this out. The CSS looks good. As we move forward with the new block editor however the focus on the classic editor, which now only exists as a plugin, will diminish, so I'm afraid this will not be picked up anytime soon. You could consider bringing it up in the support forum for the plugin ​https://wordpress.org/plugins/classic-editor/#developers if you'd still like to get this done. In any case we look forward to seeing your next contributions :)
