I'm not sure if I've understood correctly, but, that draft seems to suggest
that in Firefox you *may* be able to set user-select, either in the parent
element or in the before/after pseudo element itself:
Note: As of the time of writing, experimental implementations do not all
behave like this. Firefox does.
So, in essence, something like:
element::before {
user-select: text;
...
}
You could also try moz-user-select but try the above first.
Again, I'm not sure I've read enough of the draft to gain complete
understanding. The fact it's a draft is a red flag -- indeed, the entire
section is denoted "at risk".
Here's the MDN article, for reference (no mention of pseudo elements)
