Incorrect syntax highlighting for Go

[findleyr]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.86.2
• OS Version: Windows 10 Enterprise

Steps to Reproduce:

1. Install VS Code 1.86.2
2. Create a file main.go, with the following contents:

package main

func main() {
  var s []byte = []byte("]")
  println(s)
}

3. Observe that println is highlighted as a string -- the "]" highlighting is not terminated at the closing ". Here's a related screenshot from one of our users. (Please ignore that the Go extension is installed in this screenshot, the issue reproduces without the Go extension.)
   

I'm one of the maintainers of the Go extension. This was reported to us in golang/vscode-go#3158, but appears to be a recent regression in VS Code 1.86, not the Go extension. Per the 1.86 release notes, this was likely broken by the switch to https://github.com/worlpaker/go-syntax.

dup of #205005

https://marketplace.visualstudio.com/items?itemName=golang.Go does not supply its own go grammar
but instead relies on VSCode's builtin go grammar
which changed in 1.86

Thanks. I'll close as a dupe.
