<p dir="auto">When I typed $this in PHP files, I selected auto-complete $this, then it becomed $$this actually.</p>
<p dir="auto">When using autocompletion for variables it places 2 dollar signs instead of 1. For example typing <math-renderer class="js-inline-math" style="display: inline" data-static-url="https://github.githubassets.com/static" data-run-id="85a35ae9805c83ee8a7ab305f211edbb">$_GET will transform it into $</math-renderer>$_GET. Fails with every completion starting with $.</p>
