Created attachment 476794 [details] Example of broken syntax highlighting Minimal example: ``` <!DOCTYPE html> <html lang="en"> <script> const x = undefined const foo = x?.value console.log(`${1234}`) console.log("bye") </script> <body> </body> </html> ``` In the attachment, you can see that the code > `) > console.log("bye") it starts to be highlighted as a string. If you remove the `?` , the backlight works correctly
