Description

<input className={(condition ? "value" :"otherValue")} />

Causes hinting and linting to stop working and loads CPU until VScode is killed manually.

Disabling this add-on resolved the issue. VSCode: 1.23.1 Add-on v0.0.15

Contributor guide

Research direction
Investigate the regex or parsing logic that handles class names in JSX expressions, specifically focusing on why ternary operators cause high CPU usage. Look for infinite loops or catastrophic backtracking in the extension's tag rename logic.
