Drag&drop task that is outside of visible timeline

Question

Dear Syncfusion Team,Recently I've modified our Gantt solution with better task visibility in gantt - to inlcude tasks that are not contained by timeline, but start/end data is with range.Everything works well expect drag&drop  - as when task is wayy outside of timeline and user triggers drag&drop - it modifies date to either start, or end of timeline.Example: timeline start (dd.MM.yyyy): 01.04.2019- end 08.07.
2019

task starts 10.03.2019, lasts for 26 days - once dragged it automatically moves to start date of 
01.04.2019

(no way to drag between 10.03 ad 31.03)Below scenario in stackblitz ('Peform soil test' task) :https://stackblitz.com/edit/angular-ga7zr6-4t1k1p?file=data.ts,app.component.ts,app.component.html I would be grateful for any tips, or future feature request for that scenario,Best regards,KJ
