[Bug] css class & pseudo element bug

[ljm12914]

🐞 Bug Report

Describe the bug

• When a CSS class selector (.class) is followed by a pesudo element (etc. ::after) with a space, which will select the descendent of this class, is minified, the space is lost, causing the style to be only applied to the very element which has the class attribute.

---

Is this a regression?

I don't know it very clearly.

---

To Reproduce

1. Create a .css file
2. Write something like .class ::after{}
3. Right click and choose "Minify this Document and preserve the original" (Other options will reproduce the bug as well)
4. See error: The space in the middle of .class ::after{} was lost.

---

Expected behaviour

This space should not be minified.

It happens to me also, for example in .separator :hover {... the space before :hover is lost.
Any chance to fix this bug within a reasonable time?
