Parsing error of number value in minified CSS

[yahooshiken]

Hello. First of all, I would like to thank you for this great project!
This issue is trivial and edge case.

Only when I used the "-minify" option ( [email protected] ), my CSS codes were not parsed correctly.
For example

input.css

a {
  opacity: .0;
}

output.css

a{opacity:}

I think this problem is caused by esbuild removing trailing zeros and unnecessary decimal point in internal/css_parser/css_parser.go.

Simply modifying internal/css_parser/css_parser.go as described below can solve this problem.
However, I'm not a specialist in Go lang, so maybe there is a more sophisticated solution.

func mangleNumber(t string) (string, bool) {
	original := t

	if dot := strings.IndexByte(t, '.'); dot != -1 {
+		if dot == 0 {
+			t = "0" + t
+			dot++
+		}

		// Remove trailing zeros
		for len(t) > 0 && t[len(t)-1] == '0' {
			t = t[:len(t)-1]
		}

		// Remove the decimal point if it's unnecessary
		if dot+1 == len(t) {
			t = t[:dot]
		} else {
			// Remove a leading zero
			if len(t) >= 3 && t[0] == '0' && t[1] == '.' && t[2] >= '0' && t[2] <= '9' {
				t = t[1:]
			} else if len(t) >= 4 && (t[0] == '+' || t[0] == '-') && t[1] == '0' && t[2] == '.' && t[3] >= '0' && t[3] <= '9' {
				t = t[0:1] + t[2:]
			}
		}
	}

	return t, t != original
}

Thank you for reading.
Best regards.
