Hi Michael,
Thanks for your interest in syncfusion products.
I am afraid that I was not able to see the issue in the sample. I have created a minimal sample as per your requirement. Could you please give us the reproduce steps in that sample or send us the sample that reproduce the issue, so that we could try to find the solution and provide you the exact solution early?
Here is the sample:
