@kostajh it looks like the Dialog header is set to have a dividing line in the header on scroll only or am I misinterpreting the codex design? Also in the image where the header dividing line is shown, we can also see scroll is enabled.

... or, as @eigyan says, I am misinterpreting the designs, and the dialogs shouldn't have any border unless there is overflow content. Looking again at the Codex dialog examples, the only one that shows a border is the one with overflowing content. In which case, we can decline this task. @JSengupta-WMF, please let me know what you prefer to do for this task.

Per Codex, there's no border below the title ("Report Incident") on the desktop dialog component. There is for mobile.
