Blazor - MouseEventArgs.Type property is always null in .NET 6.0

[AsMich]

Hi,
In my Blazor .NET 5.0 project, I used one delegate function for several mouse events, e.g .:

<img @OnClick="OnMouseEvent" @ondblclick="OnMouseEvent" @OnMouseMove="OnMouseEvent" />

@code {
async Task OnMouseEvent(MouseEventArgs e) {
switch (e.Type)
{
case "click":
//...
break;
case "dblclick":
//...
break;
case "mousemove":
//...
break;
//...

After upgrading the project to .NET 6.0, the Type property of MouseEventArgs parameter is always null.
Is it intentional or is it a bug?

Thanks a lot

Looks like a bug in the framework. I'd reported it earlier - #32397 - but didn't realize this is also a regression. This might be patch-worthy. In the meanwhile, you could change your callbacks to specify the type e.g.:

<img @OnClick="(e) => OnMouseEvent(e, "click")" ...

async Task OnMouseEvent(MouseEventArgs e, string type) {
   switch (type) { // e.Type is not currently populated.
}
