[Bug] Inconsistent behaviour when using on css file

[sambora1313]

🐞 Bug Report

Describe the bug

When trying to minify css document some sort of irregular behaviour happens-> If I select all content in css document and go with option "minify the selected text", the output code doesn't work as id did before (doesn't render, or it does partly). Then I tried to minify same document, but "per partes". So I went through and selected parts of the code and minified it. Part after part. Finally I minified all parts together (4 or 5 blocks of the minified code to 1), and the code was OK - it was rendering as expected. I couldn't catch what was the cause of the problem. But it seems that the behaviour of the css minifier is not consistent.

---

Expected behaviour

• I would expect consistent output code. If "per partes" minifying works, it should also when all of the code is being minified at once.

---

Media prove

• source css - rendering OK
• minified css - "per partes" - rendering OK
• minified css - with "minify the selected text" - rendering broken
• test site - currently using minified css - "per partes"

Your environment

• OS: Windows 10 (21H2, 19044.2075)
• Visual Studio Code: v1.72.1
• MinifyAll: v2.10.0
