Error in identifier/syntax prevents autocommands to be executed

dunric commented 5 months ago

What did you do? (required: The issue will be closed when not provided)

create a new empty project, initialize with go mod init
create a new main.go file with following-like contents:
```
package main
```

func main() { report() // function defined in other file }

 3. create a new file `other.go` in the same project's root directory:
```go
package main

import "fmt"

// error in keyword fnc ⇒ func
fnc report() {
    fomt.Println("vim-go")   // error in module identifier fomt ⇒ fmt
}

open main.go in gVim. Autocommands defined in .vimrc get executted.
open within the same session other.go with :edit command. Autocommands are not executed.

defined in .vimrc

" This won't get executed when subsequent file contains an invalid syntax
autocmd FileType go setlocal tabstop=4 noexpandtab foldmethod=syntax

What did you expect to happen?

Autocommands for FileType go will be triggered, despite some syntactic errors, just based on file's extension .go .

What happened instead?

Autocommands were not run, when other.go was opened as the second file. Curiously, when other.go is opened as the first one, FileType based autocommands are executed, despite the same contents with syntactic errors.

Autocommands are also executed when other.go contents is fixed and valid, even when opened as the second one. Seems it may be related to gopls response which subsequently will prevent autocommands to be triggered.
