Describe the bug

Using a component named Script.razor produces an intellisense error:

In a component, write:

<Script />

• Intellisense detects it as the script tag (which it isnt):

Element 'Script' is a container element and must have separate closing tag.

To Reproduce

• Create a component with file name Script.razor. Leave content as default (so that we see whether it's used or not)
• in Index.razor, add the component: <Script />.
• Notice the warning

This happens with both 3.1 and 5.0-preview.
