I realized the Type="InputType.Number" allows one to enter letter e but it is only supposed to allow numbers. I also printed the e to the console since i suspected it was the base of logs but it printed an empty line. I also realized you can't enter more than one e in the textbox. I think it's a bug.
The package I was using was the latest stable as of today, Syncfusion.Blazor.Inputs (version=27.1.58).
