HTML syntax highlighting broken by inline script tag

[mathiasvr]

The HTML syntax highlighting can be broken by inserting an inline script tag with if condition.

• VSCode Version: 1.42.1
• OS Version: macOS 10.14.6

Steps to Reproduce:

1. Insert <script>if (1) {}</script> or <script>if (1) func()</script> into an HTML file.
2. Syntax highlighting is broken.

This can generally be worked around by adding a closing semi-colon.
The first example can also be worked around by removing a space: <script>if (1){}</script>.

Does this issue occur when all extensions are disabled?: Yes/No
