Thank you for contacting Syncfusion support.
We have checked your provided code block and the attached image. We suspect that you have improperly applying the styles for e-fullrow class element or having improper way to modify the tree node element structure using TreeView component DrawNode method. Could you please ensure those scenarios at your end?

Thanks for the update.
We have analyzed your provided code block and the reported issue at our end. But, your shared code blocks are not having these problems and it is working fine at our end. We suspect that “z-index” style applied for e-fullrow element in your application. Could you please ensure this at your end?
As like your scenario, we have rendered our TreeView in Modal Dialog and prepared a sample using your provided code blocks.
