Some time, when two events follow each over in the scheduler, and when the zooming level make them drawn with a very small width, they can appear as overlapping (each event on its own line), when they would normally appear on the same line (for example with other zoom levels).
This occur with pair of events where the next one start at the same time than the previous one end, or even if there is a one minute delay between them. Also it occurs because we use the setting "useEventBoxes: 'Never'".
I attach a small code example that reproduces this issue. And a screenshot of how it looks on my computer.
For us, it is an issue because it confuses our users to believe that they have overlapping activities in their production plan when they look at the overview zoom level.
