Self closing tag for components in .razor triggers intellisense usage

Type: Bug

Writing the self closing tag myself will trigger autocomplete and insert first suggestion(like #, % or --cssvar).

I have disabled every extension except C#, restarted vscode as well.

I have tested it in a brand new dotnet new blazor -int webassembly -n test app, created this component:

Components/Hello.razor
<p>hellp @SecondWord</p>
@code
{
    [Parameter] public string SecondWord { get; set; }
}

Home.razor

<Hello SecondWord="world"
<Hello SecondWord="world" /
<Hello SecondWord="world" @/_blank></Hello>

Seems like / is not canceling the auto complete

Steps to Reproduce

1. Open a FIle.razor file with ASP.NET Razor as language (blazor component)
2. Open a component tag using <MyComponent Prop1="2" |
3. Self close the tag by typing SHIFT + 7 and SHIFT + < (german keyboard, should result in />)
4. When / is inserted, intellisense will jump in and suggests random stuff; when i add the last char > to it it results in this:
5. • <IcomGap Gap="4" /%></IcomGap> instead of .."4" />
6. Can be avoided by pressing ESC for every single button press, thats not what i want to do lol

Expected behavior

1. <IcomGap Gap="4"
2. <IcomGap Gap="4" / – / pressed
3. <IcomGap Gap="4" /> – > pressed

Actual behavior

1. <IcomGap Gap="4"
2. <IcomGap Gap="4" / – / pressed
3. <IcomGap Gap="4" /%></IcomGap> – > pressed
