Description

I'm not sure this is a bug or feature, but my understanding is that with "Autocomplete Brackets" enabled and including backticks, that this should work.

Steps to Reproduce

1. Add this to a JS file: ```js
   const something = abc;
   const another = `
   multi-
   line
   `;

2. Use the key command `ctrl-m` while next to one of the backticks<!-- Second Step -->

**Expected behavior:**

<!-- What you expect to happen -->

It would jump to the matching backtick.

**Actual behavior:**

It jumped somewhere else (to a nearby curly bracket even though I wasn't clicking near a curly bracket). 

**Reproduces how often:**

It seems consistent now, though I could swear it was working for single line backticks before.
