[Blazor WASM] Component named "Col" breaks razor syntax #8460

Open ShockwaverReal opened 1 year ago

ShockwaverReal commented 1 year ago

Is there an existing issue for this?

Describe the bug

If a component is named "Col" it strangely breaks razor syntax when used inside code brackets and indentation when used in (not necessarily self-)cascade.

Expected Behavior

It to work like other components, eg:

Steps To Reproduce

  1. Create base WASM project
  2. Create client component named "Col"
  3. Use component inside razor code brackets

Exceptions (if any)

Project won't compile and errors are shown as if the "Col" tag was unrecognized/unclosed

Hi, is there any news on this? Even just a confirmation of the odd behavior and that I'm not doing something wrong?

Thank you kindly.

Hi, thanks for reporting the issue. I can reproduce the problem and will investigate.

@ShockwaverReal the issue happens when you use components named as HTML void tags (e.g., <Input>, <Col>) in code blocks (i.e., @{ }). Void tags cannot contain any children in normal HTML and currently that applies also to components in code blocks (because the text after the start tag is parsed as C# code since the parser considers start void tags as self-closed).
