My apologies in advance if there is some other forum I am supposed to use for SPO questions, but I could not find it. I have worked on multiple tenants in SPO and no matter what tenant I am working on, when I select a Web Part to Chrome setting to be Title and Border, the border never shows. If I use Border Only, it does show.
This behavior appears to be related only to SPO, because every SharePoint 2013 On Premise farm I have worked on does not behave this way.
I have tried to change themes, etc. and nothing works. I am able to make the borders show if I use CSS in a Script Editor web part, but I want the border to show for only specific web parts, and that would be cumbersome to have CSS that refers to specific web parts, so I would like to avoid it.
Has anyone else experienced this issue and is there a way to fix this behavior?
