How to reproduce using the stackblitz demo:

Thank you for the clarification. It seems that the problem is in the following code: https://github.com/DevExpress/DevExtreme/blob/a7c2d7d83d716dbb1ef6a7926f0c36d4ba9a59ee/js/ui/scheduler/ui.scheduler.work_space.js#L1665

Hi. How @Telem says, the problem is still appearing after the new release.
To reproduce the problem it is necessary to click over the tamplates.
Here is a gif using the updated version with https://stackblitz.com/edit/angular-ibh8ch?file=package.json
