Substantial Lag in Displaying Edit Dialog Box

[Zhi Yuan]

Hello,

I've tried running the code in the tutorial: https://blazor.syncfusion.com/documentation/datagrid/editing/#dialog

However, I noticed that there's a substantial lag in both the first & subsequent loads of the Dialog Box, though the subsequent loads are faster. I've done some simple performance profiling using Chrome Devtools and have attached the following images for your reference.

In delay_first.png, I clicked the "Add" button at ~1100ms, and it only appeared after ~3600ms. Total duration: ~2500ms

In delay_subsequent.png, I clicked the "Add" button at ~1800ms, and it only appeared after ~2550ms. Total duration: ~750ms

I would have thought that displaying an empty Dialog Box should be rather immediate, is this an issue?

Thank you!
