I have this code in my app: () => console.log(`Finished executeNavigationStep(${stepName})`) The syntax highlighter matches the ")" inside the string with the opening parens. See attachment

Strange. We use CodeMirror 4.2 and support for template strings was apparently added in 4.1: http://codemirror.net/doc/releases.html There is bug 1132557 for upgrading to a newer version, but if the bug is still there on the web-hosted version, this should be reported to the CodeMirror issue tracker.

Actually, Template strings work, but the parens inside the template string is badly matched.

It seems to work with latest version of CodeMirror (I tried directly on the website's examples). Let's see what happens after an upgrade then :)

I think this works now; I tried a simple example with both debuggers and it seemed ok. There have been several CodeMirror upgrades in-tree since comment #3. So, I'm marking this as fixed.
