Blazor bind:after description is incorrect on the "Blazor Data binding" page.

Description

The description of how to use bind:after contains the following text:

To execute asynchronous logic after binding, use @bind:after="{EVENT}" with a DOM event for the {EVENT} placeholder. An assigned C# method isn't executed until the bound value is assigned synchronously.

I think this contains a (very confusing, IMO) cut-and-paste error from the earlier code about bind:event, which (correctly) reads:

Bind a property or field on other DOM events by including an @Bind:event="{EVENT}" attribute with a DOM event for the {EVENT} placeholder.

But the @bind:after attribute does not have a value which which is a DOM event. It has a value that's the name of a method (or delegate) to be called after the event has occurred. It should probably read something more like like:

To execute asynchronous logic after binding, use @bind:after="{DELEGATE}" . An assigned C# method [perhaps this should read "delegate" instead?] isn't executed until the bound value is assigned synchronously.

This problem was there in the 8.0 docs (maybe earlier) and is still in the 10-preview docs.

Yes, I see what you mean. I'll take your suggestion on this and try to get a PR up by EOD to resolve it. Thanks for calling it out.

Actually! I have a minute ... but only a minute 😆 ... to address this. I'll place your suggestion now for review with the product unit.
