问题
I installed a fresh copy of WebStorm and opened up an existing Angular project.
When I open up any HTML file in the project the IDE shows 'Cannot find div' for all div tags in the .html file. For a few seconds the IDE is fine, then it shows a '2.5.3 Typescript' tab with a list of TypeScript errors.
Some Typescript tab errors:
Error:(1, 2) TS2304: Cannot find name 'div'.
Error:(3, 4) TS2304: Cannot find name 'div'.
Error:(3, 9) TS2304: Cannot find name 'ngIf'.
I've tried invalidating the cache and restarting. I've tried disabling TSLint. I've tried injecting language for some of the attributes/tags.
Even index.html throws a bunch of TypeScript errors.
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title></title>
<base href="/">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="icon" type="image/x-icon" href="">
</head>
<body>
</body>
</html>
I expect no red squiggly marks in the .html file since it is all valid. It works fine in VS Code.

Known issue, WEB-36373 is fixed in 2018.3.3.
For now, I can suggest turning Angular language service off in Settings | Languages & Frameworks | TypeScript (all the angular functionality will still be available)
