Our client reported an issue with published reports.
It appears that most if not all visuals with line values are broken when report is publish to Power Bi Service. Same problem with at least line chart, line and stacked column chart, line and clustered column chart and area chart.
Here's a default view of a published demo report (link to pbix below), at this point everything is as intended.
Now when I shift the scrollbar below each visual just one day to the right. Each and every line disappears, data labels are still there, but the lines are nowhere to be seen.
Problem appears in most browsers, I tested Chrome, IE and Edge myself. In some cases these visuals will crash IE11.
