• Issue type: bug
• Extension Name: vscode-autoprefixer
• Extension Version: 3.0.0
• OS Version: MacOS Catalina 10.15.3
• VSCode Version: 1.43.2

I'm finding that the autoprefixer is attempting to run on all files, instead of just CSS/SCSS. It's started doing this only in the last couple of months (not sure when exactly sorry).

I can still run the prefixer with ctrl+shift+C but cannot use Format On Save at the moment, as it throws up this error every time I'm saving a file that isn't CSS/SCSS (screenshot below):

[Autoprefixer]
Cannot execute Autoprefixer because there is not supported languages. Supported: LESS, SCSS, PostCSS and CSS.

Any help would be appreciated, cheers.
