I’ve found you added some code to fix below issues in 6.1.7 * Fix bug in the [Multiselect extension](https://docs.dhtmlx.com/gantt/desktop__multiselection.html) which caused selected tasks to lose highlight after chart repaint
But it causes another issue !! I can not get task item selected, cause isSelected method is replaced with multi-selected ext.
It is SO FRUSTRATED when you deliver code that is not full tested and have low quality, it causes us too much issues, this is how you deliver you product?
You should really check multi-selected is turned on or off !!!
Please, give me more details about the use case and reproduce the issue in the snippet, then click on the “Share” button and send me the link: https://snippet.dhtmlx.com/3a7e741de
Thank you for the clarification and for sending the snippet.
I added the bug in the tracker, the dev team will fix it in future versions, sorry for the inconvenience. Unfortunately, I cannot give you any ETA.
