Use case or problem
When I embed a different page to another file, in the preview mode, it will show the embed title, but in the exported pdf, it won’t, I hope both of them can be in the same format. More info
Proposed solution
Either make the file title in preview mode disappear and I add a heading to it manually or add the file title to the exported pdf. As WhiteNoise mentioned, the another solution is make a css snnipet
Current workaround (optional)
Ignoring it
