Hi there,
We've found an issue where if certain tasks are filtered and then a task is indented, the indented task is displayed in an incorrect manner and there may also be duplication.
Steps to Reproduce
- Go to the advanced demo here: https://www.bryntum.com/examples/gantt/advanced/
- Using the cell editors, change the progress of "Install Apache" to 10%
- Change the progress of "Configure firewall" to 30%
- Change the progress of "Setup load balancer" to 20%
- Change the progress of "Configure ports" to 40%
- Add a filter on progress/% done for less than 25%
- Right-click on "Setup load balancer" and indent
You'll see that it now appears at the top of the schedule, indented but under no parent. When deactivating the filter, it gets redrawn in the correct place but is now seemingly duplicated.
