When looking at a task for a project in timeline view, it is possible to move the milestones. However when the filter is selected where 'Milestones = yes' then it is possible to only move one milestone and then no more. There is nothing in the logs and the browser doesn't show activity in the network console.
STEPS TO REPRODUCE:
1. Open Clarity in Modern UX and create a Project with several task including at least 4 Milestones
2. Go into Timeline view
3. Drag a few of Milestone tasks across page and all is good so far
4. Now create a filter and let Milestone = Yes
5. Try to move the Milestone task across page
Expected Results: Milestone tasks can be moved across the Timeline view page
Note: That other items such as Dates or Status cannot be changed on other Milestones either, it is not just dragging the timeline.
Actual Results: Only the one Milestone task can be moved across page. None of the others move
