Weird backticks behavior in JS code

[mileskin]

Backticks behave strangely with the extension, at least in JS.

Without extension: when I type two backticks, two backticks appear and cursor is positioned after the backticks. When I press left arrow, cursor moves between the backticks, and I can start typing stuff.

With extension: when I type two backticks, two backticks appear and the cursor is positioned already between the backticks (this is nice, no need to move the cursor). However, when I start typing, the cursor moves to the right hand side of the backticks (obviously broken behavior). Alternatively, if I press left arrow (when to cursor is between the backticks), a new backtick appears on the left side of the initial backticks (again broken behavior).
